Abstract

Inspired by the scenario 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\mathcal{P}\mathcal{P}', QQ\mathcal{Q}\mathcal{Q}', RR\mathcal{R}\mathcal{R}') and three electrons. The electron spin on GaAs quantum dots PP\mathcal{P}\mathcal{P}' is used to encode the unknown qubit. The GaAs quantum dot QQ\mathcal{Q}\mathcal{Q}' and RR\mathcal{R}\mathcal{R}' combine to form {an} entangled state. Alice (the sender) performs a Bell measurement on pairs (P,Q\mathcal{P},\mathcal{Q}) and (P,Q\mathcal{P}',\mathcal{Q}'). Depending on the outcome of {the} measurement, a suitable Hamiltonian for the quantum gate can be used by Bob (receiver) to transform the information based on {a} spin to charge-based information. This work offers relevant corrections to misconception in {\it Chem. Phys. Lett. {\bf421} (2006) 338.
