Reference-frame-independent Quantum secure direct communication
Jia-Wei Ying, Shi-Pu Gu, Xing-Fu Wang +7
Current quantum secure direct communication (QSDC) protocols guarantee communication security by estimating the error rates of photons in the X and Z bases. This take the reference…
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…
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…
Maximal Steered Coherence in Accelerating Unruh-DeWitt Detectors
Hong-Wei Li, Yi-Hao Fan, Shu-Ting Shen +6
Quantum coherence, a fundamental aspect of quantum mechanics, plays a crucial role in various quantum information tasks. However, preserving coherence under extreme conditions, suc…
Device-independent quantum secret sharing with noise preprocessing and postselection
Qi Zhang, Wei Zhong, Ming-Ming Du +5
Device-independent (DI) quantum secret sharing (QSS) can relax the security assumptions about the devices' internal workings and provide QSS the highest level of security in theory…
Device-independent quantum secret sharing with advanced random key generation basis
Qi Zhang, Jia-Wei Ying, Zhong-Jian Wang +9
Quantum secret sharing (QSS) enables a dealer to securely distribute keys to multiple players. Device-independent (DI) QSS can resist all possible attacks from practical imperfect…
