Toward Heisenberg-Limited Interferometry with Dual Squeezers
Yi Gu, Song-Ping Wang, Wei Zhong
The canonical Mach-Zehnder interferometer fed with a coherent state and a squeezed-vacuum state of equal intensities is theoretically predicted to achieve Heisenberg scaling in pha…
Entropic Uncertainty Relations with Quantum Memory in Accelerated Frames via Unruh-DeWitt Detectors
Ming-Ming Du, Hong-Wei Li, Shu-Ting Shen +5
Quantum uncertainty is deeply linked to quantum correlations and relativistic motion. The entropic uncertainty relation with quantum memory offers a powerful way to study how share…
Robust hyperentanglement self testing
Yu-Hao Wang, Xing-Fu Wang, Ming-Ming Du +4
Hyperentanglement, which refers to entanglement encoded in two or more independent degrees of freedom (DOFs), is a valuable resource for the future high-capacity quantum network. C…
Basis-independent Coherence in Noninertial Frames
Ming-Ming Du Yi-Hao Fan, Hong-Wei Li, Shu-Ting Shen +5
We investigate the behavior of basis-independent quantum coherence between two modes of a free Dirac field as observed by relatively accelerated observers. Our findings reveal thre…
Phase estimation in lossy optical interferometry without a reference beam
Jun Tang, Dong-Qing Wang, Wei Zhong +2
We investigate phase estimation in a lossy interferometer using entangled coherent states, with particular focus on a scenario where no reference beam is employed. By calculating t…
High-efficient long-distance device-independent quantum secret sharing based on single-photon sources
Qi Zhang, Cheng Zhang, Wei Zhong +3
Device-independent quantum secret sharing (DI QSS) relaxes security assumptions of experimental devices to provide the highest security level for QSS. Previous DI QSS protocols req…
