Asymmetric Bidirectional Controlled Teleportation by using a Seven-qubit Entangled State

Abstract

We propose a new protocol of asymmetric bidirectional controlled teleportation by using a seven-qubit entangled state as the quantum channel. That is to say Alice wants to transmit an arbitrary single-qubit state to Bob and Bob wants to transmit an arbitrary twoqubit state to Alice via the control of the supervisor Charlie. One only need perform the Bell-state measurements and single-qubit measurement.

Generation and Application of Nested Entanglement in Matryoshka Quantum Resource-States

“…The resource-state can also be used for bidirectional quantum teleportation. Bidirectional Controlled Quantum Teleportation (BCQT) protocols have been proposed for multi-qubit resource states, such as fivequbit [69], six-qubit [70,71], seven-qubit [34, 72,73] and eight-qubit states [74]. Bidirectional Controlled Quantum Teleportation can teleport arbitrary states between two users under the supervision of a third party.…”

“…Zha et al proposed the first scheme for BCQT of single qubit states using a maximally entangled seve-qubit quantum state [34]. There have been schemes proposed for BCQT that utilise states with the same number of qubits as the quantum channel being used, and thereby realise bidirectional teleportation of arbitrary singleand two-qubit states under the controller Charlie [72,73].…”
