Abstract 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 P P ′ , Q Q ′ , R R ′ ) and three electrons. The electron spin on GaAs quantum dots P P ′ is used to encode the unknown qubit. The GaAs quantum dot Q Q ′ and R R ′ 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).
