Probabilistic teleportation and entanglement matching
Wanli Li, Chuan‐Feng Li, Guang‐Can Guo · Physical Review A · 2000
Teleportation may be interpreted as sending and extracting quantum information through quantum channels. In this report, it is shown that to get the maximal probability of exact teleportation through a partially entangled quantum channel, the sender (Alice) need only operate a measurement that satisfies an ``entanglement matching'' to this channel. An optimal strategy is also provided for the receiver (Bob) to extract the quantum information by adopting a general evolution.
