Quantum Communication With Polarization-Encoded Qubit Using Quantum Error Correction

摘要

One of the most promising physical properties for implementation of quantum technology is light polarization. However, since light polarization is a fragile property, the use of quantum error correction (QEC) is a crucial issue in order to make quantum information over optical network feasible. In this direction, this paper discusses optical setups for quantum error correction in quantum communication setups based on light polarization. In particular, we show how to use the QEC setup to provide error-free entanglement distribution and its use in an error-free probabilistic teleportation setup. Then, we discuss the performance of the error-correction setup in a very noisy channel. Finally, we show that the same QEC setup can also be used to correct bipartite of qubit states.
