Scalable Tensor Network Simulation for Quantum-Classical Dual Kernel
Mei Ian Sam, Tai-Yu Li·Feb 1, 2026
This paper presents an efficient and scalable tensor network framework for quantum kernel circuit simulation, alleviating practical costs associated with increasing qubit counts and data size. The framework enables systematic large-scale evaluation o...
Noise-Resilient Quantum Chemistry with Half the Qubits
Shane McFarthing, Aidan Pellow-Jarman, Francesco Petruccione·Feb 1, 2026
Sample-based quantum diagonalization (SQD) offers a powerful route to accurate quantum chemistry on noisy intermediate-scale quantum (NISQ) devices by combining quantum sampling with classical diagonalization. Here we introduce HSQD, a novel half-qub...
Wigner Function Shapelets I : formalism
Shun Arai·Feb 1, 2026
We extend shapelets for the analysis of galaxy images to be available in a phase space, introducing \textit{Wigner Function Shapelets (WFS)}. Whereas conventional shapelets expand images separately in configuration or Fourier space using Hermite-Gaus...
Adaptive Quantum-Safe Cryptography for 6G Vehicular Networks via Context-Aware Optimization
Poushali Sengupta, Mayank Raikwar, Sabita Maharjan +2 more·Feb 1, 2026
Powerful quantum computers in the future may be able to break the security used for communication between vehicles and other devices (Vehicle-to-Everything, or V2X). New security methods called post-quantum cryptography can help protect these systems...
Electro-optic conversion of itinerant Fock states
Thomas Werner, Erfan Riyazi, Samarth Hawaldar +10 more·Jan 31, 2026
Superconducting qubits are a leading candidate for utility-scale quantum computing due to their fast gate speeds and steadily decreasing error rates. The requirement for millikelvin operating temperatures, however, creates a significant scaling bottl...
Noise Resilient 1SDIQKD for Practical Quantum Networks
Syed M Arslan, Muhammad T Rahim, Asad Ali +2 more·Jan 31, 2026
One-sided device-independent quantum key distribution (1SDI-QKD) offers a practical middle ground between fully device-independent protocols and standard QKD, achieving security with detection efficiencies as low as 50.1\% on the untrusted side. Howe...
Energy Absorption Interferometry
Stafford Withington, Willem Jellema·Jan 31, 2026
Energy Absorption Interferometry (EAI) is a technique for measuring the responsivities and complex-valued spatial polarimetric forms of the individual degrees of freedom through which a many-body system can absorb energy. It was originally formulated...
Pauli Cloners for Pauli Channels
S. F. Kerstan, M. Gallezot, T. Decker +2 more·Jan 31, 2026
We present a quantum circuit architecture for the one-to-two cloning of $N$-qubit registers. It implements the broad class of Pauli cloners by extending the Niu--Griffiths architecture to multi-qubit systems. In the single-qubit case, we provide expl...
Practical Quantum Reservoir Computing in Rydberg Atom Arrays
Dong-Sheng Liu, Qing-Xuan Jie, Chang-Ling Zou +2 more·Jan 31, 2026
Quantum reservoir computing (QRC) is a promising quantum machine learning framework for near-term quantum platforms, yet the performance of different QRC architectures under realistic constraints remains largely unexplored. Here, we provide a compara...
A room-temperature cavity-magnonic source of correlated microwave pairs
Qiuyuan Wang, Aravind Karthigeyan, Chung-Tao Chou +1 more·Jan 30, 2026
Correlated microwave photon sources are key enablers for technologies in quantum-limited sensing, signal amplification and communication, but the reliance on millikelvin operating temperature limits their scalability for broader applications. Here, a...
Topological Defects from Quantum Reset Dynamics
R. Jafari, Henrik Johannesson, Sebastian Eggert·Jan 30, 2026
We analyze mechanisms for universal out-of-equilibrium dynamics near criticality by exploring the effect of randomized quantum resetting (QR) under a finite-time quench across a quantum phase transition. Using the transverse-field Ising chain as a ge...
Robust multiparameter estimation using quantum scrambling
Wenjie Gong, Bingtian Ye, Daniel Mark +1 more·Jan 30, 2026
We propose and analyze a versatile and efficient multiparameter quantum sensing protocol, which simultaneously estimates many non-commuting and time-dependent signals that are coherently or incoherently coupled to sensing particles. Even in the prese...
Margin-Based Generalisation Bounds for Quantum Kernel Methods under Local Depolarising Noise
Saarisha Govender, Ilya Sinayskiy·Jan 30, 2026
Generalisation refers to the ability of a machine learning (ML) model to successfully apply patterns learned from training data to new, unseen data. Quantum devices in the current Noisy Intermediate-Scale Quantum (NISQ) era are inherently affected by...

Sudha, B. N. Karthik, K. S. Akhilesh +1 more·Jan 30, 2026
Phase sensing with entangled multiqubit states in the presence of noise is a central theme of modern quantum metrology. The present work investigates Dicke state superposition probes for quantum phase sensing under parameter encoding generated by one...
Scattering of Squeezed Light by a Dielectric Slab
Ghafoor Pooseh·Jan 30, 2026
We develop a quantum theory for the scattering of squeezed coherent light by a dissipative dielectric slab. Using the Green-function quantization approach, we derive the transformation of the field quadratures and show how dispersion, absorption, and...
Orders of magnitude sampling overhead reduction in quantum error mitigation
Raam Uzdin·Jan 30, 2026
Quantum error mitigation (QEM) infers noiseless expectation values from noisy variants of a target quantum circuit. Unlike quantum error correction, QEM requires no additional hardware resources and is therefore routinely employed in experiments on c...
