The SpinPulse library for transpilation and noise-accurate simulation of spin qubit quantum computers
Benoît Vermersch, Oscar Gravier, Nathan Miscopein +6 more·Jan 15, 2026
We introduce SpinPulse, an open-source python package for simulating spin qubit-based quantum computers at the pulse-level. SpinPulse models the specific physics of spin qubits, particularly through the inclusion of classical non-Markovian noise. Thi...
Cloud parameter estimation for interacting BEC after time-of-flight
Rasmus Malthe Fiil Andersen, Stine Frederiksen, Laurits Stokholm +4 more·Jan 15, 2026
Experiments on Bose-Einstein condensates at finite temperature typically extract the system parameters, such as temperature, atom number, and condensed fraction from time-of-flight images taken after a free expansion time. This paper systematically e...
Coherence Limits in Interference-Based cos(2$\varphi$) Qubits
S. Messelot, A. Leblanc, J. -S. Tettekpoe +4 more·Jan 15, 2026
We investigate the coherence properties of parity-protected $\cos(2\varphi)$ qubits based on interferences between two Josephson elements in a superconducting loop. We show that qubit implementations of a $\cos(2\varphi)$ potential using a single loo...
QDsiM: A Noise-Aware Simulation Toolkit for Quantum Diamond Microscope
Satyam Pandey, Abhimanyu Magapu, Prabhat Anand +2 more·Jan 15, 2026
The nitrogen-vacancy (NV) center in diamond is a leading solid-state platform for room-temperature quantum magnetometry owing to its long spin coherence times, optical spin initialization and readout, and high sensitivity to magnetic, electric, and t...
Topology-Aware Block Coordinate Descent for Qubit Frequency Allocation of Superconducting Quantum Processors
Zheng Zhao, Weifeng Zhuang, Yanwu Gu +3 more·Jan 15, 2026
Pre-execution calibration is a major bottleneck for operating superconducting quantum processors, and qubit frequency allocation is especially challenging due to crosstalk-coupled objectives. We establish that the widely-used Snake optimizer is mathe...
Autonomous Quantum Simulation through Large Language Model Agents
Weitang Li, Jiajun Ren, Lixue Cheng +1 more·Jan 15, 2026
We demonstrate that large language model (LLM) agents can autonomously perform tensor network simulations of quantum many-body systems, achieving approximately 90% success rate across representative benchmark tasks. Tensor network methods are powerfu...
Computing Statistical Properties of Velocity Fields on Current Quantum Hardware
Miriam Goldack, Yosi Atia, Ori Alberton +1 more·Jan 15, 2026
Quantum algorithms are gaining attention in Computational Fluid Dynamics (CFD) for their favorable scaling, as encoding physical fields into quantum probability amplitudes enables representation of two to the power of n spatial points with only n qub...
Classical simulation of a quantum circuit with noisy magic inputs
Jiwon Heo, Sojeong Park, Changhun Oh·Jan 15, 2026
Magic states are essential for universal quantum computation and are widely viewed as a key source of quantum advantage, yet in realistic devices they are inevitably noisy. In this work, we characterize how noise on injected magic resources changes t...
Hybrid Quantum Algorithms for Computational Chemistry: Application to the Pyridine-Li ion Complex
Fatemeh Ghasemi, Yousung Kang, Yukio Kawashima +1 more·Jan 15, 2026
Accurately capturing electron correlation in large-scale molecular systems remains one of the foremost challenges in quantum chemistry and a primary driver for the development of quantum algorithms. Classical configuration-interaction methods, while ...
Three Months in the Life of Cloud Quantum Computing
Darrell Teegarden, Allison Casey, F. Gino Serpa +4 more·Jan 15, 2026
Quantum Computing (QC) has evolved from a few custom quantum computers, which were only accessible to their creators, to an array of commercial quantum computers that can be accessed on the cloud by anyone. Accessing these cloud quantum computers req...
Beyond Optimization: Harnessing Quantum Annealer Dynamics for Machine Learning
Akitada Sakurai, Aoi Hayashi, Tadayoshi Matsumori +3 more·Jan 14, 2026
Quantum annealing is typically regarded as a tool for combinatorial optimization, but its coherent dynamics also offer potential for machine learning. We present a model that encodes classical data into an Ising Hamiltonian, evolves it on a quantum a...
Lattice fermion simulation of spontaneous time-reversal symmetry breaking in a helical Luttinger liquid
V. A. Zakharov, J. Sánchez Fernán, C. W. J. Beenakker·Jan 14, 2026
We extend a recently developed "tangent fermion" method to discretize the Hamiltonian of a helical Luttinger liquid on a one-dimensional lattice, including two-particle backscattering processes that may open a gap in the spectrum. The fermion-doublin...

Daryoosh Vashaee, Jahanfar Abouie·Jan 14, 2026
We present an analytically tractable theory of reservoir-engineered refrigeration of a superconducting microwave cavity and map it onto a realistic solid-state implementation based on gate-defined double-quantum-dot (DQD) spin qubits. Treating the DQ...
