Query: Continuous-variable measurement-device-independent quantum key
  distribution with photon subtraction   It has been found that non-Gaussian operations can be applied to increase and
distill entanglement between Gaussian entangled states. We show the successful
use of the non-Gaussian operation, in particular, photon subtraction operation,
on the continuous-variable measurement-device-independent quantum key
distribution (CV-MDI-QKD) protocol. The proposed method can be implemented
based on existing technologies. Security analysis shows that the photon
subtraction operation can remarkably increase the maximal transmission distance
of the CV-MDI-QKD protocol, which precisely make up for the shortcoming of the
original CV-MDI-QKD protocol, and 1-photon subtraction operation has the best
performance. Moreover, the proposed protocol provides a feasible method for the
experimental implementation of the CV-MDI-QKD protocol.
