Distributed Quantum Dynamics on Near-Term Quantum Processors
Vladyslav Bohun, M. Grandadam, M. Koch-Janusz·Feb 5, 2025
Simulations of quantum dynamics are a key application of near term quantum computing, but are hindered by the twin challenges of noise and small device scale, which limit the executable circuit depths and the number of qubits the algorithm can be run...
Contextuality of Quantum Error-Correcting Codes
Derek Khu, Andrew Tanggara, Chao Jin +1 more·Feb 4, 2025
Universal fault-tolerant quantum computation requires overcoming the Eastin--Knill theorem on quantum error correction (QEC) codes that protect information from noise. This is often accomplished through strategies like magic state distillation, which...

M. Per, N. Rhodes, Maiyuren Srikumar +1 more·Feb 4, 2025
Quantum computers have the potential to revolutionise our understanding of the microscopic behaviour of materials and chemical processes by enabling high-accuracy electronic structure calculations to scale more efficiently than is possible using clas...
Developing techniques for Simulation of SU(3) Quantum Field Theories on State-of-the-Art Quantum Devices
I. Chernyshev·Feb 4, 2025
Quantum computing has long been an experimental technology with the potential to simulate, at scale, phenomena which on classical devices would be too expensive to simulate at any but the smallest scales. Over the last several years, however, it has ...
Efficient Magic State Cultivation on the Surface Code
Yotam Vaknin, Shoham Jacoby, Arne Grimsmo +1 more·Feb 3, 2025
Magic state cultivation is a leading approach for generating the resource states required for fault-tolerant quantum computation. Here we present a new cultivation protocol that increases the success probability of magic-state generation in platforms...
Solid neon as a noise-resilient host for electron qubits above 100 mK
Xinhao Li, Christopher S. Wang, Brennan Dizdar +7 more·Feb 3, 2025
Solid neon can be used as a solid host for single-electron qubits, and at temperatures of around 10 mK, electron-on-solid-neon charge qubits exhibit long coherence times and high operation fidelities. However, systematic characterization of the noise...
Expedited Noise Spectroscopy of Transmon Qubits
Bhavesh Gupta, V. Joshi, Udit Kandpal +3 more·Feb 2, 2025
There has been tremendous progress in the physical implementation of quantum protocols in recent times, bringing us closer than ever to realizing the promise of quantum computing. However, environmental noise continues to pose a crucial challenge to ...
Embedding of Tree Tensor Networks into Shallow Quantum Circuits
S. Sugawara, Kazuki Inomata, Tsuyoshi Okubo +1 more·Jan 31, 2025
Variational Quantum Algorithms (VQAs) are being highlighted as key quantum algorithms for demonstrating quantum advantage on Noisy Intermediate-Scale Quantum (NISQ) devices, which are limited to executing shallow quantum circuits because of noise. Ho...
Limits of Information Flow Between Classically Interacting Particles
Miles D. Miller-Dickson, Christopher Rose·Jan 30, 2025
Pinning down a precise understanding of information flow within physical interactions remains a central concern to fields like stochastic thermodynamics and quantum information science. In both spheres a careful accounting of bits (or qubits) enables...
Enhancing Quantum Expectation Values Via Exponential Error Suppression and CVaR Optimization
Touheed Anwar Atif, Reuben Tate, S. Eidenbenz·Jan 30, 2025
Precise quantum expectation values are crucial for quantum algorithm development, but noise in real-world systems can degrade these estimations. While quantum error correction is resource-intensive, error mitigation strategies offer a practical alter...
Real-time adaptation of quantum noise channel estimates
