Robustness of the projected squeezed state protocol

BJ Alexander, JJ Bollinger, MS Tame - Physical Review A, 2024 - APS
Projected squeezed (PS) states are multipartite entangled states generated by unitary spin
squeezing, followed by a collective quantum measurement and postselection. They can lead …

Experimental detection of initial system–environment entanglement in open systems

G Zhu, D Qu, L **ao, P Xue - Photonics, 2022 - mdpi.com
We experimentally investigate how initial entanglement between the system and
environment can be detected in an open system by using some prior knowledge of the joint …
