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

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 proposed. The teleportation is carried out using three GaAs quantum dots (say $P$, $Q$, $R$) and three electrons. The electron spin on GaAs quantum dot $P$ is used to encode the unknown qubit. The GaAs quantum dot $Q$ and $R$ combine to form {an} entangled state. We perform a Bell measurement and depending on the outcome of {the} measurement, a suitable Hamiltonian for the quantum gate can be used to transform the information based on {a} spin to charge-based information.
