Remote preparation and manipulation of squeezed light
Remote state preparation enables one to create and manipulate a quantum state
based on the shared entanglement between distant nodes. Here, we experimentally
demonstrate remote preparation and manipulation of squeezed light. By
performing homodyne projective measurement on one mode of the continuous
variable entangled state at Alice's station, a squeezed state is created at
Bob's station. Moreover, rotation and displacement operations are applied on
the prepared squeezed state by changing the projective parameters on Alice's
state. We also show that the remotely prepared squeezed state is robust against
loss and N-1 squeezed states can be remotely prepared based on a N-mode
continuous variable Greenberger-Horne-Zeilinger-like state. Our results verify
the entanglement-based model used in security analysis of quantum key
distribution with continuous variables and have potential application in remote
quantum information processing
