Quantum teleportation with mutually unbiased bases

During the realization of one-qubit quantum teleportation, an EPR pair shared between two parties is required, followed by a joint Bell state measurement on the teleported qubit and the sender’s qubit. In this paper, we analyze the joint measurements in the case of teleporting multiple qubits. By carefully dividing the sender’s qubit space into several subspaces, we show that the receiver can restore the qubits if the measurement is taken in the mutually unbiased basis. We generalize our protocol to teleporting special entangled states and high-dimensional state. Our protocol may have potential application in multi-qubit quantum teleportation.
