Quantum error modelling and correction in long distance teleportation using singlet states

Year: 2002
Type: dissertation
Abstract: Under a multidisciplinary university research initiative (MURI) program, researchers at the Massachusetts Institute of Technology (MIT) and Northwestern University (NU) are developing a long-distance, high-fidelity quantum teleportation system.This system uses a novel ultrabright source of entangled photon pairs and trapped-atom quantum memories.This thesis will investigate the potential teleportation errors involved in the MIT/NU system.A single-photon, Bell-diagonal error model is developed that allows us to restrict possible errors to just four distinct events.The effects of these errors on teleportation, as well as their probabilities of occurrence, are determined.Techniques drawn from quantum error correcting codes and entanglement purification protocols are investigated as means for reducing teleportation errors in the MIT/NU architecture.Finally we apply existing bounds on the achievable rate of reliable quantum communication to the MIT/NU system.
