Tobias Starke·Jan 8, 2026
In this work we present an intuitive construction of the quantum logical axiomatic system provided by George Mackey. The goal of this work is a detailed discussion of the results from the paper 'Physical justification for using the tensor product to ...
Distinguishing Coherent and Incoherent Errors in Multi-Round Time-Reversed Dynamics via Scramblons
Zeyu Liu, Pengfei Zhang·Jan 8, 2026
Despite the rapid development of quantum science and technology, errors are inevitable and play a crucial role in quantum simulation and quantum computation. In quantum chaotic systems, coherent errors arising from imperfect Hamiltonian control and i...
Unconditionally teleported quantum gates between remote solid-state qubit registers
Mariagrazia Iuliano, Nicolas Demetriou, H. Benjamin van Ommen +3 more·Jan 8, 2026
Quantum networks connecting quantum processing nodes via photonic links enable distributed and modular quantum computation. In this framework, quantum gates between remote qubits can be realized using quantum teleportation protocols. The essential re...
Floquet-driven tunneling control in monolayer MoS$_2$
Rachid El Aitouni, Aotmane En Naciri, Clarence Cortes +2 more·Jan 8, 2026
We study how fermions in molybdenum disulfide MoS$_2$ interact with a laser field and a static potential barrier, focusing on the transmission probability. Our aim is to understand and control photon-assisted quantum transport in this two-dimensional...
Noise tailoring for error mitigation and for diagnozing digital quantum computers
Thibault Scoquart, Hugo Perrin, Kyrylo Snizhko·Jan 8, 2026
Error mitigation (EM) methods are crucial for obtaining reliable results in the realm of noisy intermediate-scale quantum (NISQ) computers, where noise significantly impacts output accuracy. Some EM protocols are particularly efficient for specific t...
PACOX: A FPGA-based Pauli Composer Accelerator for Pauli String Computation
Tran Xuan Hieu Le, Tuan Hai Vu, Vu Trung Duong Le +2 more·Jan 8, 2026
Pauli strings are a fundamental computational primitive in hybrid quantum-classical algorithms. However, classical computation of Pauli strings suffers from exponential complexity and quickly becomes a performance bottleneck as the number of qubits i...
Quantum Wiener architecture for quantum reservoir computing
Alessio Benavoli, Felix Binder·Jan 8, 2026
This work focuses on quantum reservoir computing and, in particular, on quantum Wiener architectures (qWiener), consisting of quantum linear dynamic networks with weak continuous measurements and classical nonlinear static readouts. We provide the fi...
Fast thermal state preparation beyond native interactions
Alexander van Lomwel, Paul M. Schindler, Modesto Orozco-Ruiz +3 more·Jan 8, 2026
While questions on quantum simulation of ground state physics are mostly focussed on the realization of effective interactions, most work on quantum simulation of thermal physics explores the realization of dynamics towards a thermal mixed state unde...
Bound state solutions with a linear combination of Yuakawa plus four-parameter diatomic potentials using path integral approach: Thermodynamic properties
Mohamed Améziane Sadoun, Redouane Zamoum, Abdellah Touati·Jan 8, 2026
In this paper, we investigate the approximate analytical bound states with a linear combination of two diatomic molecule potentials, Yukawa and four parameters potentials, within the framework of the path integral formalism. With the help of an appro...
Topological sensing of superfluid rotation using non-Hermitian optical dimers
Aritra Ghosh, Nilamoni Daloi, M. Bhattacharya·Jan 8, 2026
We theoretically investigate a non-Hermitian optical dimer whose parameters are renormalized by dispersive and dissipative backaction from the coupling of the passive cavity with a ring-trapped Bose-Einstein condensate. The passive cavity is driven b...

Nicholas S. Yama, Chun-Chi Wu, Fariba Hatami +1 more·Jan 8, 2026
The efficient interfacing of quantum emitters and photons is fundamental to quantum networking. Quantum defects embedded in integrated nanophotonic circuits are promising for such applications due to the deterministic light-matter interactions of hig...
The Role of Quantum in Hybrid Quantum-Classical Neural Networks: A Realistic Assessment
Dominik Freinberger, Philipp Moser·Jan 8, 2026
Quantum machine learning has emerged as a promising application domain for near-term quantum hardware, particularly through hybrid quantum-classical models that leverage both classical and quantum processing. Although numerous hybrid architectures ha...
Regularization from Superpositions of Time Evolutions
Eliahu Cohen, Tomer Shushi·Jan 8, 2026
Short-time approximations and path integrals can be dominated by high-energy or large-field contributions, especially in the presence of singular interactions, motivating regulators that are suppressive yet removable. Standard regulators typically im...
SurgeQ: A Hybrid Framework for Ultra-Fast Quantum Processor Design and Crosstalk-Aware Circuit Execution
Xinxuan Chen, Hongxiang Zhu, Zhaohui Yang +4 more·Jan 8, 2026
Executing quantum circuits on superconducting platforms requires balancing the trade-off between gate errors and crosstalk. To address this, we introduce SurgeQ, a hardware-software co-design strategy consisting of a design phase and an execution pha...
Construction of asymptotic quantum many-body scar states in the SU($N$) Hubbard model
