Gain tuning and fidelity in continuous-variable quantum teleportation

Abstract

The fidelity of continuous-variable teleportation can be optimized by changing the gain in the modulation of the output field. We discuss the gain dependence of fidelity for coherent, vacuum, and one-photon inputs and propose optimal gain tuning strategies for corresponding input selections.

Improving the fidelity of continuous—variable quantum teleportation by tuning displacement gain

刘金明, 李剑, 郭光灿

The fidelity of teleportation of continuous quantum variables can be improved by tuning the local displace-ment gain. We investigate the optimization of the fidelity for the teleportation of Schrodinger cat states,and of coherent states. It is found that the gain corresponding to the maximum fidelity is not equal to onefor the two input states in the case of the small squeezing degree of the entanglement resource, while unitydisplacement gain is the best choice for teleporting arbitrary quantum states in the case of large squeezing.

Gain tuning for continuous-variable quantum teleportation of discrete-variable states

We present a general formalism to describe continuous-variable (CV) quantum teleportation of discrete-variable (DV) states with gain tuning, taking into account experimental imperfections. Here the teleportation output is given by independently transforming each density matrix element of the initial state. This formalism allows us to accurately model various teleportation experiments and to analyze the gain dependence of their respective figures of merit. We apply our formalism to the recent experiment on CV teleportation of qubits [S. Takeda et al., Nature 500, 315 (2013)] and investigate the optimal gain for the transfer fidelity. We also propose and model an experiment for CV teleportation of DV entanglement. It is shown that, provided the experimental losses are within a certain range, DV entanglement can be teleported for any nonzero squeezing by optimally tuning the gain.
