Fast, high-fidelity Transmon readout with intrinsic Purcell protection via nonperturbative cross-Kerr coupling
Guillaume Beaulieu, Jun-Zhe Chen, Marco Scigliuzzo +5 more·Jan 8, 2026
Dispersive readout of superconducting qubits relies on a transverse capacitive coupling that hybridizes the qubit with the readout resonator, subjecting the qubit to Purcell decay and measurement-induced state transitions (MIST). Despite the widespre...
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...
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...
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...
Implementation of Tensor Network Simulation TN-Sim under NWQ-Sim
Aaron C. Hoyt, Jonathan S. Bersson, Sean Garner +2 more·Jan 7, 2026
Large-scale tensor network simulations are crucial for developing robust complexity-theoretic bounds on classical quantum simulation, enabling circuit cutting approaches, and optimizing circuit compilation, all of which aid efficient quantum computat...
Transmutation based Quantum Simulation for Non-unitary Dynamics
Shi Jin, Chuwen Ma, Enrique Zuazua·Jan 7, 2026
We present a quantum algorithm for simulating dissipative diffusion dynamics generated by positive semidefinite operators of the form $A=L^\dagger L$, a structure that arises naturally in standard discretizations of elliptic operators. Our main tool ...
$\mathsf{QAC}^0$ Contains $\mathsf{TC}^0$ (with Many Copies of the Input)
Daniel Grier, Jackson Morris, Kewen Wu·Jan 6, 2026
$\mathsf{QAC}^0$ is the class of constant-depth polynomial-size quantum circuits constructed from arbitrary single-qubit gates and generalized Toffoli gates. It is arguably the smallest natural class of constant-depth quantum computation which has no...
Quantum-enhanced long short-term memory with attention for spatial permeability prediction in oilfield reservoirs
Muzhen Zhang, Yujie Cheng, Zhanxiang Lei·Jan 6, 2026
Spatial prediction of reservoir parameters, especially permeability, is crucial for oil and gas exploration and development. However, the wide range and high variability of permeability prevent existing methods from providing reliable predictions. Fo...
