Teleportation with two-dimensional electron gas formed at the interface of a GaAs heterostructure

Inspired by the scenario proposed by Bennett et al, a teleportation protocol of qubits formed in a two-dimensional electron gas formed at the interface of a GaAs heterostructure is presented. The teleportation is carried out using three GaAs quantum dots (say PP', QQ', RR') and three electrons. The electron spin on GaAs quantum dots PP' is used to encode the unknown qubit. The GaAs quantum dot QQ' and RR' combine to form an entangled state. Alice (the sender) performs a Bell measurement on pairs (P, Q) and (P', Q'). Depending on the outcome of the measurement, a suitable Hamiltonian for the quantum gate can be used by Bob (the receiver) to transform the information based on spin to charge-based information. This work offers relevant corrections to the misconception in Weng and Kais (2006 Chem. Phys. Lett. 421 338).
