Abstract

Photon subtraction (PS) is a widely used technique in the distillation of noise-damped continuous-variable Gaussian entangled states. In the literature, all distillation schemes with the PS technique are restricted to pure Gaussian entanglement or amplitude-damped entanglement, and it is not clear whether PS is applicable in overcoming the phase noise or even more general noise. In this paper, we show that the PS technique is versatile and can still be used to distill entanglement that is subject to phase noise and simultaneous phase and amplitude noise.
