Quantum advantage prediction in turbulent free-space quantum illumination
Yu Tang, Beining Xia, Qianqian Liu +3
Quantum illumination offers a significant theoretical advantage for target detection in high background noise environments. However, its practical deployment in free-space channels…
Macroscopic Optical Nonreciprocity: A Black Hole as an Optical Diode
Wentao Liu, Di Wu, Xiongjun Fang +2
Optical reciprocity--the principle that light retraces the same path when source and detector are interchanged--is a foundational concept in geometric optics. In this Letter, we de…
Survival of nonclassical correlations in Lorentz-violating spacetime
Yangchun Tang, Zhilong Liu, Wentao Liu +1
The breakdown of Lorentz invariance, a potential signature of quantum gravity, offers a window into physics beyond general relativity. We investigate how such a violation, embodied…
Accelerating Black Hole Image Generation via Latent Space Diffusion Models
Ao Liu, Xudong Zhang, Lin Ding +3
Interpreting horizon-scale black hole images currently relies on computationally intensive General Relativistic Ray Tracing (GRRT) simulations, which pose a significant bottleneck…
Escape of quantum information across an analogue black hole horizon
Zhilong Liu, Wentao Liu, Zehua Tian +1
The complete evaporation of black holes, as a natural endpoint of Hawking radiation, gives rise to the black hole information paradox, which fundamentally challenges the principles…
Quantum coherence of continuous variables in the black hole quantum atmosphere
Xiaofang Liu, Cuihong Wen, Jieci Wang
Recently, the concept of quantum atmosphere has been introduced as a potential origin of Hawking quanta. This study investigates the properties of quantum fields by exploring the q…
