Monte Carlo simulations model complex quantum interactionsquantum-computing

Monte Carlo simulations model complex quantum interactions

Researchers at Swinburne University of Technology are promoting transparency in quantum research by making their data and simulation codes openly available via Harvard Dataverse, created in 2025. Published on August 24, 2026, their work details Monte Carlo wave-function simulations used to analyze the coherent coupling strategy for coherent Ising machines, quantum networks designed to solve complex optimization problems. These simulations, involving Hilbert spaces exceeding 107 dimensions, offer a path toward exploring the limits of quantum performance for this NP-hard problem without relying on potentially limiting Gaussianity assumptions. The authors state that quantum computational advantage has been an important motivation for quantum computing researchers. The study was accepted for publication on July 15, 2026. Monte Carlo Wave-function Simulations Model CIM Interactions Researchers are leveraging Monte Carlo wave-function simulations to analyze the coherent Ising machine (CIM) in regimes previously inaccessible to conventional modeling techniques, pushing the boundaries of quantum optimization research. These simulations, conducted by a team at Swinburne University of Technology, utilize Hilbert spaces exceeding 107 dimensions to accurately represent the complex interactions within the CIM, a quantum network designed to solve the NP-hard Ising model. The team’s approach circumvents limitations inherent in master equation methods, which become computationally prohibitive as system size increases, and avoids the inaccuracies of Gaussian approximations when dealing with non-Gaussian quantum states. To facilitate open science and reproducibility, the data and simulation codes underpinning this work are openly available through Harvard Dataverse; Manushan Thenabadu, Run Yan Teh and P D Drummond created “CIM Project Codes for Numerical Simulation, Version 1.1 (2025)”. This commitment to transparency allows other researchers to verify the findings and build upon thi

Soongsil University Team Estimates Ground-State Energy with 0.00 mHa Deviation

Researchers at Soongsil University and collaborating institutions have demonstrated a hybrid quantum-classical approach for calculating molecular ground-state energies using Sample-Based Quantum Diagonalization (SQD). The study evaluates the molecular systems HeH⁺, ArH⁺, and H₂O, showing that the technique can accurately reproduce potential-energy curves while operating within the capabilities of today’s quantum hardware. The results demonstrate that SQD can achieve accuracy comparable to established quantum chemistry methods, highlighting its potential as a practical tool for studying increasingly complex molecular systems on near-term quantum computers. Until now, accurate ground-state energy calculations for molecules required computationally demanding methods like coupled-cluster singles and doubles (CCSD). The deviations from complete active space configuration interaction references were as low as 0.00 mHa for HeH^+, demonstrating the accuracy of this new approach for benchmark systems. The team successfully applied SQD to helium hydride ion, argon hydride ion, and water, validating its potential for broader use in understanding molecular behaviour and astrophysical systems. Unlike traditional methods, such as coupled-cluster singles and doubles (CCSD), which are akin to painstakingly assembling a complex jigsaw puzzle requiring significant computational resources, SQD builds up a picture of a molecule’s lowest energy state by taking many ‘snapshots’ from a quantum computer and combining them, much like creating a detailed mosaic from individual tiles. This is particularly significant as CCSD, while highly accurate, scales poorly with system size, becoming intractable for all but the smallest molecules. The team successfully applied SQD to helium hydride ion, argon hydride ion, and water, achieving deviations from benchmark calculations as low as 0.00 mHa for helium hydride ion. This demonstrates the potential of SQD for complex systems and offers a pathway to

Granthi: Higher-Order Quantum Programming via Unitary Wiring

This paper presents Granthi, a purely unitary higher-order quantum programming language built on three design commitments: quantum programs are first class values that may be passed, returned, and coherently composed; additive structure is tag-preserving routing rather than observational branching, so control may remain in superposition; and programmer-facing finite label types with named reversible operations provide domain-level control spaces without exposing tag management. Every well-typed term, including at function type, denotes a unitary on its boundary interface, and the compiler realizes exactly its wiring as a quantum circuit on the physical qubit layout (assuming correctness of the pytket backend). Granthi is implemented end-to-end: an OCaml DSL elaborates surface programs through a binder-free core IR to executable quantum circuits via pytket. The language directly supports the quantum switch, compiled to a static circuit, as well as interference on control-flow history and structured finite control, all within the purely unitary fragment.

To Scale Up or To Scale Out: Evaluating Space-Time Costs of Compiled Logical Circuits on Modular Superconducting Quantum Processors

--> Quantum Physics arXiv:2608.20462 (quant-ph) [Submitted on 20 Aug 2026] Title:To Scale Up or To Scale Out: Evaluating Space-Time Costs of Compiled Logical Circuits on Modular Superconducting Quantum Processors Authors:Nikiforos Paraskevopoulos, Sebastian de Bone, Mick Christophersen, Simon Storz, A. Mert Bozkurt, Arno Bargerbos, Sebastian Feld View a PDF of the paper titled To Scale Up or To Scale Out: Evaluating Space-Time Costs of Compiled Logical Circuits on Modular Superconducting Quantum Processors, by Nikiforos Paraskevopoulos and 6 other authors View PDF HTML (experimental) Abstract:Modular integration has emerged as the main pathway for scaling superconducting quantum processing units (QPUs) beyond the constraints of fabrication yield and physical footprint. Currently, two primary strategies lead this effort. Mirroring the "Scaling Up" and "Scaling Out" approaches in GPU architectures and AI infrastructures, these are: chiplet-based scaling, which preserves dense connectivity and high gate fidelity at the expense of engineering complexity, and distributed architectures, which decouple system scaling from monolithic QPU advancements at the expense of sparser connectivity and lower interconnect quality. To evaluate these approaches, we introduce a quantitative stress test measuring the execution cost of a dense workload of random logical entangling operations using a surface code scheme. Using a dedicated compiler, we compute the space-time cost as the number of network nodes increases, analysing this scaling behaviour across various surface code distances, Bell-state fidelities, and Bell-pair generation times. We find that distributed architectures incur an up to exponential space-time performance penalty compared to an effectively monolithic architecture across all simulations. Our results also show that as the network grows, this penalty manifests in two distinct scaling regimes: a noise-dominated regime constrained by insufficient Bell-state fidelity an

Quantum phase estimation for nondestructive monitoring and Wigner tomography of bosonic fields

Santos, Ciro M. Diniz, Daniel Z. Rossatto, Celso J. Villas-Boas View a PDF of the paper titled Quantum phase estimation for nondestructive monitoring and Wigner tomography of bosonic fields, by Lucas R. S. Santos and 3 other authors View PDF HTML (experimental) Abstract:Quantum phase estimation is usually introduced as an algorithmic primitive for extracting eigenphases of unitary operators. Here we show that, when implemented through a dispersive light-matter interaction, it can also be used as a nondestructive measurement tool for bosonic fields. We consider a bosonic mode coupled to a multi-qubit register and calibrate the photon-number dependent phase shifts so that the register performs a number-resolved quantum phase estimation readout. Repeating this readout during dissipative evolution enables nondestructive monitoring of photon-number dynamics. We then show that the same readout can be converted into a Wigner tomography reconstruction by applying phase-space displacements before the quantum phase estimation block. Numerical reconstructions for Fock, coherent, and even/odd Schrödinger cat states show the expected nonclassical phase-space structures and near-unity Wigner overlap fidelities. The protocol provides a unified route to nondestructive monitoring and state tomography of bosonic fields, with direct relevance for bosonic-state characterization, calibration, and control in superconducting quantum architectures.

Brookhaven Lab and Stony Brook send quantum data through the air

Researchers at Brookhaven National Laboratory and Stony Brook University have achieved the first U.S. demonstration of quantum data transmitted through open air, extending the reach of the nation’s longest quantum network beyond fiber-optic cable limitations. During a demonstration on Friday, Aug. 21, scientists successfully sent light particles carrying quantum information 13 miles between the Stony Brook University’s Quantum Watchtower and Brookhaven’s Quantum Lighthouse, a rooftop facility built for this purpose. “The future of quantum information science will depend not only on what individual quantum computers and devices can do but on our ability to connect them,” said DOE Under Secretary for Science Darío Gil. This free-space optical link adds a wireless component to the network already connecting eight nodes. Free-Space Optical Link Bridges Brookhaven and Stony Brook Brookhaven National Laboratory’s Quantum Lighthouse, a dedicated rooftop facility, served as the receiving point for the first U.S. demonstration. Realized in collaboration with Stony Brook University, this achievement bypasses the limitations inherent in fiber-optic cable networks by utilizing a free-space optical link stretching 13 miles between the two institutions. 21, showcasing the precision required to maintain quantum states across such a distance. The newly established wireless component relies on an intricate system of optics and controls, integrating quantum sources and detectors across the 21-kilometer span. Justine Haupt, Brookhaven Lab’s lead scientist on the project, explained the challenges, stating, “We needed to integrate the optics, controls, communications, quantum sources, and detectors so equipment 21 kilometers apart could operate as one experiment.” This integration was crucial for maintaining the delicate quantum states of the photons as they traversed the open air, a feat complicated by atmospheric turbulence.

Diraq, Quantum Computing Built in Standard Siliconquantum-computing

Diraq, Quantum Computing Built in Standard Silicon

Diraq builds qubits the way the world builds chips. The Australian company makes them in silicon, on the same lines that turn out ordinary computer processors. It spun out of UNSW Sydney and is run by its founder, Andrew Dzurak, whose group worked on silicon qubits for two decades before the business existed. The bet is simple. If you can make a qubit on a standard production line, you can make millions of them, and millions is what a working error-corrected machine will need. That argument has drawn venture money, a United States CHIPS Act letter of intent and a place in a US defence benchmarking programme. Key takeaways 1. Silicon spin qubits in CMOS. Diraq stores quantum information in the spin of an electron, held inside a modified silicon transistor. The point is reuse. The same lines that make ordinary chips can make these. 2. UNSW Sydney spin-out. The company was founded by Scientia Professor Andrew Dzurak, who remains chief executive and founder. The underlying research program at UNSW ran for around two decades before the business launched. 3. Foundry-made qubits that hit fidelity targets. Working with imec on a 300mm line, Diraq reported unit cells with single- and two-qubit fidelities above 99 percent. Readout reached 99.9 percent. The result appeared in Nature in September 2025. 4. Hot qubits above 1 kelvin. Dzurak’s group demonstrated high-fidelity operation above 1 kelvin, far warmer than the millikelvin range of superconducting machines. Warmer operation could let control electronics sit closer to the qubits and lower cooling costs. 5. Government and venture backing. Diraq last put the total behind its technology at over 135 million US dollars, in February 2024. That figure, on the company’s own wording, already folds in Australian and American government research money. It has also signed a CHIPS Act letter of intent worth up to 38 million. 6. On DARPA’s benchmarking track. Diraq advanced to Stage B of DARPA’s Quantum Benchmarking Initiative in Novem

Parity measurements help build better quantum light sources

Researchers from East China Normal University and New York University Shanghai have developed a new protocol for preparing specialized quantum states crucial for advancing quantum technologies. The work demonstrates the generation of squeezed states, achieving approximately 9 decibels of quantum noise reduction after three parity measurements, with potential for even greater noise reduction as the number of measurements increases. This technique extends beyond squeezed states to also prepare cat and Gottesman-Kitaev-Preskill states, and the authors state the scheme is universal, allowing for the preparation of an arbitrary state. Bosonic modes utilized in this process provide long-lived degrees of freedom for quantum information storage and processing. Dispersive Measurements & Displacements: The PANDA Algorithm This work introduces the Parity/Number basis measurement Displacement Algorithm, or PANDA, a technique leveraging dispersive measurements and displacements to engineer a variety of bosonic quantum states. The PANDA algorithm’s core innovation lies in its ability to generate not only squeezed states, but also more complex states like cat and Gottesman-Kitaev-Preskill (GKP) states. These states are critical components in areas like quantum metrology and quantum communication, offering potential improvements in precision measurement and secure data transmission. The protocol hinges on the principle that a squeezed vacuum state resides exclusively within the even-parity subspace of the Fock basis, a characteristic exploited through a sequence of displaced parity measurements. By strategically applying these measurements along the anti-squeezed quadrature, the algorithm effectively isolates and prepares the desired quantum state. The team analyzed the performance of this scheme by quantifying the achievable squeezing and assessing the impact of realistic imperfections, demonstrating the robustness of the protocol. PANDA circumvents the limitation of requiring

Infleqtion (INFQ) and the Neutral-Atom Bet Behind Its NYSE Listingquantum-computing

Infleqtion (INFQ) and the Neutral-Atom Bet Behind Its NYSE Listing

Infleqtion builds quantum computers and quantum sensors out of neutral atoms, from a headquarters in Louisville, Colorado. In February 2026 it became, on its own account, the first neutral-atom specialist to trade on a major public exchange. It was founded in Boulder in 2007 as ColdQuanta by the University of Colorado physicist Dana Anderson. It then spent nearly two decades turning laboratory cold-atom physics into hardware it could ship, before listing on the New York Stock Exchange under the ticker INFQ and becoming a quantum stock overnight. The interesting question is not whether the listing happened. It is whether a business selling clocks and radio receivers today can fund a quantum computer for the 2030s. Key takeaways 1. A neutral-atom quantum company. Infleqtion builds quantum computers, precision sensors and software around neutral atoms. The company argues that this is the most scalable and economical path to commercial quantum systems. One platform, three product lines. 2. Boulder roots, founded in 2007 as ColdQuanta. The business was incorporated in Colorado on 7 February 2007 by the University of Colorado physicist Dana Anderson. It took the Infleqtion brand in November 2022, to mark the shift from research work toward selling finished products commercially. Anderson is still chief science officer. The legal entity kept the ColdQuanta name right up to the merger that took the company public. 3. The first public neutral-atom stock. The company trades on the New York Stock Exchange under the ticker INFQ after a February 2026 merger. The company says that makes it the first listed business dedicated to neutral-atom quantum technology, and the shares started trading on 17 February 2026. 4. Computing and sensing under one roof. Unlike most quantum firms, the company sells both quantum computers and a line of quantum sensors, including atomic clocks and radio-frequency receivers. A cross-vendor software stack rounds out the portfolio. 5. A staged logical-qu

Researchers classify neutrino events with a quantum computer

Researchers have achieved testing accuracy near 80% with the NPQK and approximately 70% accuracy with the QCNN in classifying events detected by neutrino telescopes using a quantum computer, a result comparable to traditional methods. Pablo Rodriguez-Grasa, University of the Basque Country UPV/EHU and colleagues demonstrated this capability by investigating neural projected quantum kernels and quantum convolutional neural networks. This work, published August 21, 2026, in Quantum Science and Technology, Number 4, establishes the feasibility of applying quantum machine learning to astronomical data analysis with current hardware. The study explores how quantum computers can distinguish between different types of neutrino events, crucial for understanding rare cosmic phenomena. NPQK and QCNN Approaches to Neutrino Event Classification Achieving testing accuracy near 80%, the neural projected quantum kernel (NPQK) approach demonstrated a capacity to classify neutrino events directly on both simulators and the IBM Strasbourg quantum processor. This result suggests a shift toward practical quantum applications in astrophysics. Researchers led by Pablo Rodriguez-Grasa at the University of the Basque Country UPV/EHU detailed this performance in a study published August 21, 2026, in Quantum Science and Technology, Number 4, focusing on distinguishing between muon tracks and hadronic/electromagnetic cascades, key signatures within neutrino telescope data. This direct implementation on quantum hardware bypasses the need for purely simulated results, validating the methodology against the inherent noise and limitations of current quantum systems. The team addressed a critical challenge in applying quantum machine learning to high-energy physics: the encoding of large feature spaces. Traditional methods struggle with the vast amounts of information generated by neutrino telescopes like IceCube, limiting the feasibility of quantum graph neural networks. To address this, Rodrigue
