Sensitivity Bounds of Multiparameter Metrology at Thermal Equilibrium
Zhu Cao
Quantum metrology aims to enhance measurement precision beyond the classical limit by leveraging quantum resources. Unlike multi-parameter dynamic quantum metrology, many questions…
Discrete-phase-randomized mode-pairing quantum key distribution
Yuewei Xu, Zeyang Lu, Chan Li +2
Mode-pairing quantum key distribution (MP-QKD) protocol achieves performance beyond the repeaterless rate-transmittance bound and exhibits excellent practicality by avoiding the re…
Loop Quantum Photonic Chip for Coherent Multi-Time-Step Evolution
Yuancheng Zhan, Hui Zhang, Rebecca Erbanni +7
Quantum evolution is crucial for the understanding of complex quantum systems. However, current implementations of time evolution on quantum photonic platforms are limited by both…
Coherent Quantum Speed Limits
Xuhui Xiao, Hai Wang, Xingze Qiu
We establish a comprehensive theoretical framework for coherent quantum speed limits (QSLs), deriving fundamental bounds on the rate of quantum evolution that explicitly isolate th…
Universally Robust Control of Open Quantum Systems
Lixiang Ding, Jingtao Fan, Xingze Qiu
Mitigating noise-induced decoherence is the central challenge in controlling open quantum systems. While existing robust protocols often require precise noise models, we introduce…
Quantum Annealing Algorithms for Estimating Ising Partition Functions
Haowei Li, Zhiyuan Yao, Xingze Qiu
Estimating partition functions of Ising spin glasses is a cornerstone of statistical physics and computational science, yet it remains classically challenging due to its P-hard…
