Abstract

Quantum trajectory equations are formulated for continuous variable teleportation, which model the generation of finite bandwidth squeezed light, the homodyne measurements carried out by Alice, and take into account the continuous feed-forward of Alice's measurement results to Bob. The formulation is multi-mode and provides direct access to correlation functions of the output field detected by Victor. Three unravellings of the dynamics are considered, corresponding to Victor's choice of direct, homodyne, or heterodyne detection of the output field. Numerical results for the teleportation of a vacuum-state input field are presented.
