Generation of distributed entangled coherent states over a lossy environment with inefficient detectors
Austin P. Lund, Timothy C. Ralph, Hyunseok Jeong · Physical Review A · 2013
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 et al., Nat. Phys. 5, 189 (2009)] and find parameters for which our scheme results in superior performance.
