Observation of quantum temporal correlations well beyond Luders bound
Chun-Wang Wu, Man-Chao Zhang, Yan-Li Zhou +10
Quantum correlations, both spatial and temporal, are the central pillars of quantum mechanics. Over the last two decades, a big breakthrough in quantum physics is its complex exten…
Switching classical and quantum nonreciprocities with spinning photonics
Yonglin Xiang, Yunlan Zuo, Xun-Wei Xu +2
We study how to achieve, manipulate, and switch classical or quantum nonreciprocal effects of light with a spinning Kerr resonator. In particular, we show that even when there is n…

We propose how to achieve synthetic symmetry in optomechanics without using any active medium. We find that harnessing the Stokes process in such a system can lead t…
Exceptional Photon Blockade: Engineering Photon Blockade with Chiral Exceptional Points
R. Huang, Ş. K. Özdemir, J. -Q. Liao +4
Non-Hermitian spectral degeneracies, known as exceptional points (EPs), feature simultaneous coalescence of both eigenvalues and the associated eigenstates of a system. A host of i…

Qi-Tao Cao, He-Ming Wang, Chun-Hua Dong +6
Chirality is an important concept that describes the asymmetry property of a system, which usually emerges spontaneously due to mirror symmetry breaking. Such spontaneous chirality…
