Robustness of entanglement in a non-Hermitian cavity-optomechanical system even away from exceptional points
Jia-Jia Wang, Yu-Hong He, Chang-Geng Liao +2
Quantum physics can be extended into the complex domain by considering non-Hermitian Hamiltonians that are -symmetric. These exhibit exceptional points (EPs) where th…

Secure quantum-enhanced measurements on a network of sensors
Sean William Moore, Jacob A. Dunningham
Two-party secure quantum remote sensing (SQRS) protocols enable quantum-enhanced measurements at remote locations with guaranteed security against eavesdroppers. This idea can be s…
