Distillation and purification of symmetric entangled Gaussian states
distillation purification symmetric entangled Gaussian
2010/11/8
We propose an entanglement distillation and purification scheme for symmetric two-mode entangled Gaussian states that allows to asymptotically extract a pure entangled Gaussian state from any input en...
Quantum Teamwork for Unconditional Multiparty Communication with Gaussian States
Quantum Teamwork Unconditional Multiparty Communication Gaussian States
2010/4/8
We demonstrate the capability of continuous variable Gaussian states to communicate multipartite quantum information. A quantum teamwork protocol is presented according to which an arbitrary possibly ...
