Robustness of the projected squeezed state protocol
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
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 …
