quantum-computingPurdue Finds Unique 2D Phonon Source of Qubit Decoherence
Researchers at Purdue University have pinpointed an origin for spin relaxation in hexagonal boron nitride, identifying the out-of-plane flexural phonon branch, unique to two-dimensional materials, as the primary source of spin relaxation in boron vacancy centers. This finding extends existing theory to a previously unaddressed regime, offering a new microscopic interpretation of observed behavior in two-dimensional quantum defect centers. The Purdue team reports quantitatively reproducing the experimental magnetic field and temperature dependence of T1 (spin-lattice relaxation time) using a microscopic theory applying acoustic mode spin-phonon relaxation, achieving this accuracy without any empirical fitting parameters. These results reveal that relaxation dynamics are driven by a direct one-phonon emission and absorption process resonant with the Zeeman splitting, occurring in the sub-THz regime. A microscopic mechanism governs qubit coherence in hexagonal boron nitride, with sound waves playing the dominant role. The researchers report these findings in their recent work, and this level of predictive accuracy underscores the robustness of their microscopic model. This mechanism, resonant with the Zeeman splitting, builds upon existing treatments focused on low-field regimes. “We show that spin relaxation in the experimentally relevant field and temperature regime is dominated by the ZA phonon branch,” the researchers state. The study’s findings offer vital insights for developing high-field quantum sensing platforms utilizing layered materials, potentially unlocking enhanced performance in nanoscale magnetometry and other applications. The pursuit of robust quantum sensors has increasingly focused on point defects in two-dimensional materials, with the boron vacancy center in hexagonal boron nitride (hBN) emerging as a leading candidate. Realizing the full potential of these sensors requires a detailed understanding of the factors influencing performance, specific

quantum-computingUniversal spin-squeezing dynamics in spinor condensates
--> Quantum Physics arXiv:2607.06842 (quant-ph) [Submitted on 7 Jul 2026] Title:Universal spin-squeezing dynamics in spinor condensates Authors:Nikolaos Giovanoudis, Navid Kazemiseresht, Fabio Mezzacapo, Emilia Witkowska, Tommaso Roscilde View a PDF of the paper titled Universal spin-squeezing dynamics in spinor condensates, by Nikolaos Giovanoudis and 4 other authors View PDF HTML (experimental) Abstract:The production of large-scale entangled states is one of the main goals of next-generation quantum technologies, with an immediate potential for applications in the context of entanglement-assisted quantum sensing. A very promising platform to achieve this goal is offered by ultracold spinor gases, made of atoms with a large internal spin sensitive to magnetic fields. Here we show that the native spin-changing collisions in a spinor Bose-Einstein condensate, combined with an arbitrary quadratic Zeeman shift, can generate scalable spin squeezing in the collective spin of the ensemble, following the universal paradigm of the celebrated one-axis-twisting model. Squeezing dynamics is driven by the quadratic Zeeman shift when this shift is small; and by the spin-changing collisions for large shifts, in the form of stroboscopic squeezing. Turning off the Zeeman shift freezes out the collective-spin dynamics, so that the ensuing collective spin dynamics can be uniquely governed by an external field to be sensed. Our theoretical results pave the way for the use of spinor Bose gases with a large spin in fundamental studies of entanglement, as well as in advanced metrological applications.

quantum-computingMillisecond coherence times in gigahertz-frequency mechanical oscillators
MainLong-lived phonons are a compelling resource, as they permit numerous quantum operations within their coherence time, which enables high-performance quantum sensors1,2,3,4, transducers5,6,7,8 and memories9,10,11. The efficient control of long-lived phonons using optomechanical12,13,14, electromechanical15,16 and superconducting qubit systems17,18,19 has generated renewed interest in phononic device physics and technologies for quantum applications20,21. Although various mechanical oscillators have produced such long-lived phonons over a range of frequencies21,22, high-frequency (gigahertz) phonons are often desirable, as they have improved immunity to unwanted noise, permit ground-state operation at cryogenic temperatures and are more readily controlled using quantum optics and circuit quantum electrodynamics techniques21,23. In theory, crystalline media are ideal for hosting such long-lived phonons, as they have vanishing internal dissipation at cryogenic temperatures24,25,26,27. However, it has proven difficult to extend the coherence times of such gigahertz-frequency crystalline oscillators to millisecond timescales.Silicon-based nanomechanical phononic crystal resonators have shown long phonon lifetimes (>1 s) at gigahertz frequencies; however, strong coupling between phonons and the two-level system limits their coherence times to ~100 μs (refs. 10,11,14). Tight phonon confinement and strong boundary reflections within these systems make them vulnerable to complex surface interactions that may contribute to excess noise and dephasing14. Alternatively, micro-fabricated high-overtone bulk acoustic-wave resonators (μHBARs) of the type seen in Fig. 1a support gigahertz-frequency phonon modes with orders of magnitude lower surface participation13,28. In principle, lower surface participation could translate to lower dephasing rates and longer coherence times. However, in practice, μHBARs have yielded modest coherence times (<1 ms)13,23, shorter than can be

quantum-computingOkayama University: Researchers Find New Material Promising for Quantum Computing Advances
Ogawa and colleagues at the University of Tokyo have recently published findings concerning the intriguing superconducting properties of K2Cr3As3. Mapping electron pairing in K2Cr3As3 using arsenic-75 nuclear magnetic resonance Nuclear magnetic resonance (NMR) proved key in discerning the subtle changes occurring within K2Cr3As3 as it transitioned between superconducting states. NMR is a spectroscopic technique that exploits the magnetic properties of atomic nuclei to provide detailed information about the material’s structure and dynamics. It detects the nuclei of atoms, revealing their magnetic environment and thus providing insights into electron behaviour. The 75As isotope was utilised, owing to its sensitivity to local spin susceptibility, to map the arrangement of paired electrons. Arsenic-75 possesses a nuclear spin of I = 3/2, making it particularly well-suited for NMR studies of magnetic materials. Its sensitivity allowed investigation of the material’s superconducting properties, offering a detailed view of electron interactions. The technique relies on applying a radiofrequency pulse to the nuclei in a strong magnetic field and observing the frequency at which they resonate, which is affected by the local magnetic environment. This allows researchers to probe the electronic structure and pairing symmetry of the superconductor. K2Cr3As3 exhibits superconductivity up to 6.2 Kelvin, a relatively high transition temperature for a Chromium-based material, and lacks long-range magnetic order which simplifies analysis. This is significant because many candidate materials for topological superconductivity suffer from the presence of competing magnetic orders that obscure the superconducting signal and complicate the interpretation of experimental results. NMR was favoured over techniques like nuclear quadrupole resonance (NQR) as it directly probes the spin state of the superconducting electrons, confirming a spin-triplet pairing mechanism. In spin-triplet pairin

A thorough review of the increasingly intertwined fields of artificial intelligence and quantum information has been completed by Min Chen of University of Pittsburgh and colleagues. The review details how AI acts as a set of tools for advancing quantum system learning, design, control, and verification, whilst quantum information presents new computational models and learning paradigms for AI development. This survey organises recent advances around key tasks including information extraction from limited measurements, quantum algorithm training and discovery, hardware stabilisation, workflow automation, and the extension of learning methods to sensing and networking. Furthermore, the work examines the impact of quantum computation and quantum-inspired structures on learning, considering algorithmic speedups, expressivity, and neural-network design, highlighting the vital need for integrated theory, experiment, and hybrid quantum-classical systems to enable overcoming challenges in reproducibility and scalability. Using tensor networks for advances in quantum and machine learning Tensor-network representations proved central to enabling these advances, functioning as a way of organising complex data into a network of interconnected nodes, similar to how a family tree shows relationships between individuals. Data represented in this interconnected format reduced the computational burden of processing high-dimensional information, a key challenge in both quantum simulations and advanced AI algorithms. These networks were used to model the intricate connections within quantum states and machine learning models, allowing for more efficient computation and analysis. The fields of artificial intelligence and quantum information are becoming increasingly intertwined.

quantum-computingHunan Normal University: Researchers Achieve Highly Pure, Indistinguishable Single Photons for Quantum Computing
A new method for generating single photons offers key components for advancing quantum technologies. Ying Ren and colleagues at Hunan Normal University demonstrate a robust scheme for deterministic single-photon emission utilising a three-level atom coupled to a single-mode cavity. The research achieves second-order correlation functions reaching approximately 10-8 under ultrastrong coupling with pulsed driving. Alongside this, photon indistinguishability exceeds $98.73\% and state purities up to 99.99\%. This near-ideal performance represents a step towards overcoming limitations in current single-photon sources and promises to accelerate progress in quantum computing and fundamental quantum optics. Demonstrated high-purity single-photon emission via ultrastrongly coupled atom-cavity systems Purity levels in this new single-photon source have now reached 99.99%, a substantial improvement over previously demonstrated methods. Achieving such high purity and indistinguishability, essential for complex quantum calculations, remained a significant obstacle until recently. Conventional sources, such as spontaneous parametric down-conversion (SPDC) and quantum dots, struggled to consistently produce photons with the required characteristics, often exhibiting multi-photon emission or lacking the necessary control over photon properties. SPDC, while relatively efficient, inherently generates photon pairs, necessitating complex filtering to isolate single photons. Quantum dots, though capable of single-photon emission, suffer from spectral wandering and limited purity. A scheme utilising a three-level atom coupled to a single-mode cavity surpasses these limitations, demonstrating an indistinguishability of 99.10% under ultrastrong coupling, and even higher values with pulsed driving. The cavity confines the light, enhancing the interaction with the atom and increasing the probability of single-photon emission, while the three-level atomic structure allows for precise control

We focus on the estimation of two relevant physical parameters, namely the temperature $T$ and the wave vector $k_x$, and analyze how their variations affect both quantum coherence and the achievable metrological precision. The minimum variances associated with the estimation process are evaluated through the quantum Cramér--Rao bound within both simultaneous and independent estimation schemes. Our results show that quantum coherence is enhanced in the low-temperature regime and around $k_x=0$, while it decreases progressively as either the temperature or the wave vector increases. However, the regions where coherence is maximal do not necessarily coincide with those of optimal estimation precision. In particular, the variance associated with temperature estimation exhibits a divergent behavior near $T=0$, indicating that the system becomes weakly sensitive to small temperature variations in this regime. By contrast, the estimation of the wave vector $k_x$ is more directly related to the coherence properties of the system, with improved precision obtained near $k_x=0$. Furthermore, we introduce the ratio $\Gamma$ to compare the total variances obtained from the independent and simultaneous estimation schemes. This quantity provides a useful measure of the relative difference between the two strategies when the parameters are estimated separately or jointly

Built upon the company’s Ramsey Coherent Population Trapping (Ramsey-CPT) interrogation platform, the system achieved a short-term fractional frequency stability metric of 1×10−13 at an interval of one second. The development track aims to establish a scalable physical architecture for compact, chip-scale atomic clocks (CSACs) targeted at infrastructure operating independently of external timing signals.

Date: July 7, 2026 Source: Vienna University of Technology Summary: A centimeter-sized crystal has revealed clear signs of quantum entanglement, showing that large, everyday objects can display surprisingly deep quantum behavior. The discovery could help solve the mystery of strange metals while opening new possibilities for ultra-precise quantum sensors and other advanced technologies. Share: Facebook Twitter Pinterest LinkedIN Email FULL STORY Proof of quantum effects in a strange metal. Credit: Harald Ritsch / TU Wien Quantum phenomena are usually associated with extremely small objects such as individual atoms, molecules, or photons that must be carefully isolated from their surroundings. But can those same strange quantum effects also exist in objects large enough to see and hold? Researchers at TU Wien have now provided compelling evidence that they can. By studying a centimeter-sized crystal made from a type of material known as a strange metal, the team detected a high degree of quantum entanglement, one of the most remarkable features of quantum physics. They accomplished this using a technique from quantum information science called quantum Fisher information. The results create a new connection between quantum information and solid-state physics by showing that quantum entanglement can be measured directly in a macroscopic strange metal.

quantum-computingUniversity of Florida Achieves Enhanced Metrology with Reversible QED
Researchers at the University of Florida and the University of Connecticut are developing a new approach to quantum metrology that utilizes reversible dynamics to access information typically hidden within entangled states. Achieving sensitivities beyond the standard quantum limit has long been a goal in the field, but extracting the encoded information has remained a central challenge. This work leverages reversible Quantum Electrodynamics, where many-body interactions serve a dual role, both generating and decoding entanglement, a key development of the past decade. The team’s research focuses on transforming weakly encoded signals into measurable observables through controlled dynamics, suggesting that the ability to decode quantum information may be as important as the ability to generate it. Quantum Metrology Beyond the Standard Quantum Limit A significant hurdle in this field remains extracting the metrological advantage encoded in fragile many-body correlations; accessing the information encoded within these delicate quantum states presents a persistent challenge. Recognizing that many-body interactions are not solely responsible for generating entanglement, but can also be harnessed to decode it, has been a key development over the past decade, offering a pathway to measurable signals. This approach centers on utilizing controlled dynamics to transform weak signals into experimentally accessible observables. Cavity quantum electrodynamics (QED) is proving to be a particularly effective environment for these techniques, combining collective enhancement with tunable and reversible interactions. Researchers at the University of Florida and the University of Connecticut are exploring how time-reversal strategies, initially rooted in the study of Loschmidt echoes and quantum reversibility, can now be repurposed as a metrological resource. This idea underlies interaction-based readout and time-reversal protocols, in which controlled nonlinear dynamics transform we

quantum-computingVeeco & k-Space Link MBE Growth to Qubit Integrity in Real Time
The delicate quantum states underpinning future computation are now subject to scrutiny during their very creation, as Veeco and k-Space Associates combine advanced material growth with real-time measurement. Researchers report that qubit coherence times, the duration a qubit maintains its state, are directly impacted by a previously understated sensitivity in quantum material fabrication. This collaboration moves beyond simply achieving process capability to integrating measurement into the growth process itself, prioritizing a deeper understanding of material development. “Quantum computing places extraordinary demands on materials quality, where even minor atomic-scale variations can significantly impact device performance,” said Matt Marek, Vice President of MBE Products at Veeco, emphasizing a shift toward valuing the ability to grow materials as much as the ability to grow materials at all. MBE & RHEED Enable Quantum Material Growth Insight The pursuit of stable qubits hinges on a narrow margin for error during material creation; even subtle atomic-scale variations can dramatically impact performance. A collaboration between Veeco and k-Space Associates exemplifies this trend, combining advanced molecular-beam epitaxy (MBE) systems with real-time metrology to provide researchers with insight into material development. Process intelligence is now considered as vital as process capability, signaling a move from merely being able to grow quantum materials to deeply understanding the growth process for improved consistency and reproducibility. Veeco MBE systems already incorporate reflection high-energy electron diffraction (RHEED), and this is frequently paired with RHEED analysis technology from k-Space.

A new method for reading out quantum information improves the sensitivity of quantum metrology. Simone Colombo and Edwin Pedrozo-Peñafiel at University of Florida, in collaboration with University of Connecticut, show that many-body interactions both generate and decode entanglement, a key step towards realising the full potential of quantum sensing. The work reviews the development of time-reversal protocols within cavity quantum electrodynamics, highlighting techniques like signal amplification through a time-reversed interaction and scrambling-enhanced metrology. Decoding quantum information is becoming increasingly vital, positioning reversible many-body dynamics as a key resource for advancing quantum-enhanced sensing technologies. Time-reversal protocols and reversible dynamics in cavity quantum electrodynamics Quantum electrodynamics (QED) is increasingly utilised due to its capacity for collective enhancement, tunable interactions, and controllable reversibility within a single platform. This review discusses the emergence of time-reversal protocols in cavity QED, tracing their development from Loschmidt echoes to modern implementations such as signal amplification through a time-reversed interaction (SATIN), scrambling-enhanced metrology, and general interaction-based readout schemes. Examining the physical mechanisms enabling reversible many-body dynamics, the article also details key experimental demonstrations and future directions involving complex entangled states, nonlinear decoding, and emerging quantum platforms. Quantum metrology exploits uniquely quantum resources to improve measurement precision beyond the standard quantum limit (SQL), which arises from the projection noise of independent particles. A broad range of entangled states, including spin-squeezed states, Dicke states, Schrödinger-cat states, and general non-Gaussian many-body states, have been proposed and realised as resources for enhanced sensing over the past decades.
