Purification of Gaussian States by Photon Subtraction
Kun Zhang, Huijun Li, Jietai Jing +2
Photon subtraction can enhance entanglement, which for pure states induces a decrease in the purity of reduced states. In contrast, by analyzing the purities of Gaussian states bef…

Teleportation of an atomic ensemble quantum state
Aurelien Dantan, Nicolas Treps, Alberto Bramati +1
We propose a protocol to achieve high fidelity quantum state teleportation of a macroscopic atomic ensemble using a pair of quantum-correlated atomic ensembles. We show how to prep…
