Tabletop reversibility of phase-covariant operations
Fangzhen Chen, Xueyuan Hu
Irreversibility and time-translation symmetry are both fundamental in open quantum dynamics, and it is of great importance to study the interplay between them. In this paper, we st…
Gaussian time-translation covariant operations: structure, implementation, and thermodynamics
Xueyuan Hu, Lea Lautenbacher, Giovanni Spaventa +3
Time-translation symmetry strongly constrains physical dynamics, yet systematic characterization for continuous-variable systems lags behind its discrete-variable counterpart. We c…
Photon counting statistics in the presence of spectral diffusion induced by nonequilibrium environmental fluctuations
Xiangji Cai, Yonggang Peng, Yujun Zheng
We theoretically investigate the statistical properties of photon emission of a driven two-level single-molecule system undergoing spectral diffusion induced by nonequilibrium envi…
Sub-Bath Cooling in Bosonic Systems: Gaussian Constraints and Non-Gaussian Enhancements
Wen-Han Png, Xueyuan Hu, Valerio Scarani
Cooling quantum systems with finite resources is a central task in quantum technologies and has been extensively explored in discrete-variable settings. As continuous-variable (CV)…
Superiority of Krylov shadow tomography in estimating quantum Fisher information: From bounds to exactness
Yuan-Hao Wang, Da-Jian Zhang
Estimating the quantum Fisher information (QFI) is a crucial yet challenging task with widespread applications across quantum science and technologies. The recently proposed Krylov…
Survival of Hermitian Criticality in the Non-Hermitian Framework
Fei Wang, Guoying Liang, Zecheng Zhao +3
In this work, we investigate many-body phase transitions in a one-dimensional anisotropic XY model subject to a complex-valued transverse field. Within the biorthogonal framework,…
