Generation of distributed entangled coherent states over a lossy environment with inefficient detectors
Abstract
Entangled coherent states are useful for various applications in quantum information processing, but they are sensitive to loss. We propose a scheme to generate distributed entangled coherent states over a lossy environment in such a way that the fidelity is independent of the losses at detectors heralding the generation of the entanglement. We compare our scheme with a previous one for the same purpose [Ourjoumtsev , Nat. Phys.1745-247310.1038/nphys1199 5, 189 (2009)] and find parameters for which our scheme results in superior performance.
