Researchers link quantum data limits to geometry and measurement

Researchers at the Technical University of Denmark’s bigQ center, working with collaborators from Finland, Germany, Korea, and Israel, have linked limits on quantum data precision to symplectic geometry, a mathematical branch typically used to study shapes and spaces. The study focuses on the Gaussian quantum Fisher information, revealing this pattern isn’t random but dictated by the underlying geometry of a quantum system. This connection builds a bridge between theoretical symplectic geometry and metrology, potentially impacting the development of more precise quantum sensors and technologies. Gaussian Quantum Fisher Information’s Even-Odd Decomposition This connection, published in Quantum Science and Technology, offers a novel approach to understanding and potentially improving data limitations in quantum technologies. The study specifically focuses on splitting the Gaussian quantum Fisher information into “even” and “odd” components; this division isn’t arbitrary, but reflects fundamental geometric properties. On pure-state manifolds, the researchers found the even contribution vanishes entirely, while the odd component aligns with the quantum Fisher information derived from the natural metric on the Siegel upper half-space, directly revealing a geometric basis for pure-Gaussian metrology. This also provides a way to express the quantum Fisher information using the graphical representation of pure Gaussian states and its parameters. The research clarifies how different types of quantum operations impact these components; for evolutions generated by passive Gaussian unitaries, specifically orthogonal symplectics, the odd quantum Fisher information disappears, with thermometric parameters contributing solely to the even sector in a predictable spectral form. The team also derived a state-dependent lower bound on the even quantum Fisher information, linked to the rate of purity change within the system. Applications to unitary sensing, comparing beam splitters to

Ytterbium atoms unlock quantum boost to 60-second magnetic coherencequantum-computing

Ytterbium atoms unlock quantum boost to 60-second magnetic coherence

Researchers affiliated with the Hefei National Research Center for Physical Sciences at the Microscale and the University of Science and Technology of China have achieved a spin coherence time of 60 seconds using ytterbium atoms, a duration that significantly exceeds typical cold-atom systems and promises more sensitive magnetic field sensors. The comagnetometer utilizes both isotopes of ytterbium, 171Yb (spin-1/2) and 173Yb (spin-5/2), jointly trapped within an optical lattice occupying approximately 160 lattice sites; vector and tensor light shifts are suppressed through polarization control and a Schrödinger cat state, respectively. This setup enables simultaneous Ramsey interferometry on both isotopes and achieves a magnetic noise suppression factor exceeding 3 x 10^4, while determining the ratio of nuclear magnetic moments to 4 parts per million precision. The results establish a new platform for spin-based sensing and may open pathways toward quantum-enhanced searches for physics beyond the Standard Model. Ytterbium Isotopes Enable Long-Coherence Comagnetometry A spin coherence time of 60 seconds achieved using ytterbium atoms represents a considerable advancement in cold-atom comagnetometry and promises enhanced sensitivity for magnetic field sensors. Researchers affiliated with the Hefei National Research Center for Physical Sciences at the Microscale and the University of Science and Technology of China in Hefei demonstrated this extended coherence by jointly trapping the isotopes ytterbium-171 and ytterbium-173 within an optical lattice, a configuration that suppresses magnetic noise and enables precise measurements. This achievement surpasses typical cold-atom coherence times. The team’s approach specifically addresses decoherence induced by light shifts, a common obstacle in utilizing cold atoms for precision measurements. The comagnetometer’s design relies on the distinct spin properties of the two ytterbium isotopes; 171Yb possesses a spin of 1/2, whil

Virginia Team Measures 3dB Squeezing on a Photonic Chipquantum-computing

Virginia Team Measures 3dB Squeezing on a Photonic Chip

Integrating the generation and measurement of squeezed light onto a single photonic chip previously presented a key challenge due to conflicting material requirements. Haoran Chen of the University of Virginia and colleagues have, for the first time, fully integrated squeezed light generation, routing, and balanced homodyne detection on a single chip using heterogeneous integration. This novel chip design overcomes a longstanding obstacle in quantum photonics by combining light generation and detection. Squeezed light, which enhances precision in measurements, demands materials that both preserve quantum properties and efficiently absorb light for detection; these needs previously required separate components. The design uses a silicon nitride chip combining a light-generating microcavity with photodiodes, achieving approximately 3 decibels of squeezing across 34 quantum modes. Squeezed light, a special state of light where the uncertainty in one property is reduced to enhance measurement sensitivity, is vital for applications like quantum sensing and advanced information processing. Creating and measuring squeezed light previously required separate components due to conflicting material needs; generating it demands materials that preserve quantum properties, while detecting it requires efficient light absorption. This integrated system provides a scalable architecture for quantum technologies, but questions remain regarding the long-term stability and potential for scaling up the number of entangled modes. Integrated quantum microcomb achieves scalable 3 dB squeezing of light Squeezed light measurements now demonstrate 3 dB of squeezing across a two-mode quantum microcomb comprising 34 quantum modes, a substantial improvement over previous systems. Previously, achieving this level of squeezing necessitated a trade-off between preserving delicate quantum states and efficiently detecting photons, limiting scalability. The integrated photonic chip, fabricated using he

Quantum Sensing Leverages ML to Track Three-Level System Phase

Researchers affiliated with the Dipartimento di Fisica e Astronomia ”Ettore Majorana”, Università di Catania, Italy have successfully trained a multi-layer perceptron (MLP) to estimate the plaquette phase within a three-level system, demonstrating a new method for extracting information using artificial intelligence. The team utilized STImulated Raman Adiabatic Passage (STIRAP) population transfer efficiencies as the data source for the machine learning model, establishing a direct link between a specific quantum control technique and AI-driven analysis. This plaquette phase profoundly affects system dynamics by breaking coherent population trapping and inducing a non-trivial phase dependence, according to the work. The results highlight how combining coherent control and machine learning enables effective phase identification, potentially opening new perspectives for quantum technologies, specifically quantum sensing applications including synthetic gauge fields. Plaquette Phase Impacts Coherent Population Trapping The subtle interplay of quantum phases can dramatically alter system behavior, and recent work demonstrates this with the identification of a phase in three-level quantum systems that profoundly affects the system dynamics, breaking coherent population trapping. The team’s findings reveal that accurately estimating this plaquette phase is now possible through a combination of established quantum control methods and machine learning. STIRAP is a well-established technique for efficiently moving quantum populations between states, but the presence of the plaquette phase introduces complexities. The researchers discovered that the efficiency of STIRAP is affected by the phase, creating a measurable signature that a machine learning algorithm can interpret. Specifically, a multi-layer perceptron (MLP), a type of machine learning, was successfully trained to estimate the plaquette phase, demonstrating a novel way to extract information from quantum systems us

Measurement incompatibility in Bayesian multiparameter quantum estimationquantum-computing

Measurement incompatibility in Bayesian multiparameter quantum estimation

AbstractWe present a comprehensive and pedagogical formulation of Bayesian multiparameter quantum estimation. Within this framework, we analyse the role of measurement incompatibility and establish its quantitative effect on attainable precision. We achieve this by deriving upper bounds based on the pretty good measurement – a notion from hypothesis testing – combined with the evaluation of the Nagaoka-Hayashi lower bound. In general, we prove that, as in the many-copy regime of local estimation theory, incompatibility can at most double the minimum loss relative to the idealised scenario in which individually optimal measurements are assumed jointly implementable. Therefore, in practical situations, the latter may provide a sufficient and computationally efficient benchmark without solving the full optimisation problem. Our results, which we illustrate through applications of discrete phase imaging, phase and dephasing estimation, and qubit sensing, provide analytical and numerical tools for assessing ultimate precision limits and the role of measurement incompatibility in Bayesian multiparameter quantum metrology, including an open-source package for all the bounds discussed here.Popular summaryQuantum technologies can enhance the precision with which physical parameters are measured. However, when several parameters are estimated simultaneously, the measurements that are individually optimal for different parameters may be incompatible—impossible to implement simultaneously. Understanding the resulting loss of precision is a central problem in quantum metrology. Most previous results address this question in a local regime, where their validity is often contingent on the parameters already being approximately known. Here, we instead study measurement incompatibility within Bayesian quantum estimation, a global framework that explicitly incorporates prior knowledge and is particularly relevant when experimental data are limited. We show that the effect of measurem

UChicago PME insight boosts potential of quantum biosensors

University of Chicago Pritzker School of Molecular Engineering and University of Iowa researchers challenged a key assumption limiting the effectiveness of diamond-based biosensors. The team initially sought to reduce sensor toxicity within living cells, but instead discovered the source of performance-limiting energy level shifts known as zero-field splitting (ZFS). According to UChicago PME Assoc. Peter Maurer, the research resolves a longstanding discussion, demonstrating these shifts are caused not by cellular temperature, but by a surface effect on the diamond itself. This greater understanding promises more detailed readings of cellular activity. Silica Coating Stabilizes Diamond Quantum Sensors Diamond-based quantum sensors, encased in a silica coating, now provide a more stable signal within living cells, resolving a long-standing debate about the origin of performance-limiting energy shifts. Peter Maurer, co-corresponding author of the published work. “So when people observed ZFS shifts they assumed that these were caused by local temperature changes, i.e., caused by cellular activities.” Coating the sensors with silica not only lessened cellular stress but also dispersed electrons, effectively eliminating performance-hindering “spin noise.” This electron loss altered the charge within the diamond, prompting a re-evaluation of the underlying physics. Crucially, the silica coating suppressed the ZFS shifts, demonstrating the surface was the primary culprit; the cell’s temperature remained consistent regardless of the coating. Experimental data confirmed the unexpected finding. “We were measuring a 5-degree change over 30 minutes inside of the cell. It’s just not thermodynamically feasible,” said Uri Zvi, first author of the paper published in Advanced Materials. This discovery allows for more precise cellular readings, potentially enabling detailed monitoring of cellular processes, such as tracking a T cell’s differentiation or identifying cancerous changes.

Argonne Lab maps atomic flaws that cause silicon qubit errors

Argonne National Laboratory researchers have mapped atomic-level flaws that directly impact the performance of silicon spin qubits, a promising platform for scalable quantum computing. The team used the Chicago Quantum Computing Testbed, the first full-stack, solid-state qubit testbed at a U.S. research institution, to analyze industrial-grade silicon wafers and pinpoint the origin of qubit failure. Their study revealed that random atomic-scale fluctuations within the silicon quantum well layers are the primary cause of variability in valley splitting, a critical energy difference affecting electron stability. This work, the researchers state, “transforms valley splitting from an unexplained obstacle into a materials engineering challenge with clear paths toward improved silicon qubits.” Atomic-Scale Disorder Correlates with Valley Splitting Variability Silicon spin qubits offer a compelling route to scalable quantum computing because they leverage established semiconductor manufacturing techniques. The research institution has pinpointed a critical factor limiting their performance: atomic-scale disorder within the silicon quantum well layers. Researchers demonstrated a direct correlation between these material imperfections and the variability of valley splitting, a quantum property impacting electron stability and qubit fidelity. The team employed a sensitive electrical spectroscopy method to map valley splitting across individual quantum dots positioned within the silicon quantum well. By shifting the quantum dot’s location and measuring the resulting changes in valley splitting, they generated a nanoscale map revealing random atomic-scale fluctuations as the dominant source of variability. These fluctuations, occurring within the alloyed quantum well, directly influence the energy difference between electron valley states; a smaller split increases the risk of electrons leaking into unwanted states, introducing errors into calculations.

Infleqtion Selected by Eaton to Support Research Advancing Quantum Computing for U.S. Grid Resilience

Multi-year, multi-million-dollar program focused on leveraging quantum computing to enhance resilience of U.S. electrical grid and reduce economic impact of power outages. LOUISVILLE, CO | August 10, 2026 | Infleqtion, a global leader in quantum computing and quantum sensing powered by neutral-atom technology, announced that Eaton, a global power management company, selected Infleqtion to support new research evaluating how quantum computing can improve the resilience of the U.S. electrical grid. As part of an Eaton award from the Air Force Research Laboratory (ARFL), Infleqtion received a subcontract to apply quantum computing hardware to support grid contingency analysis. Infleqtion and Eaton aim to advance reliability analysis used by utilities to predict and prevent cascading power outages. “Grid reliability is a large-scale optimization challenge that pushes the limits of today’s classical systems,” said Pranav Gokhale, CTO at Infleqtion. “This program allows us to explore how quantum algorithms and error-corrected quantum hardware could support faster, more accurate analysis of grid vulnerabilities to improve how we evaluate failures, reduce blackout risk, and strengthen critical U.S. infrastructure.” Contingency analysis is one of the most important tools for determining how power systems respond when key components, such as transmission lines or generators, fail unexpectedly. As power grids become more interconnected and more dependent on real-time data, the number of “what-if” scenarios grow so large that classical computing methods struggle to analyze them efficiently. Classical analysis relies on approximate methods that are often insufficient for robust risk management. This makes contingency analysis an ideal test case for quantum computing, which may evaluate complex combinations more effectively using quantum interference algorithms. Why Grid Reliability Matters for National Security and the Economy The U.S. electrical grid is increasingly stressed. E
