Bidirectional and Asymmetric Quantum Controlled Teleportation
- 176 Downloads
We propose a new protocol of bidirectional and asymmetric quantum controlled teleportation, using a maximally seven-qubit entangled state as the quantum channel. That is to say Alice wants to transmit an arbitrary single qubit state (an arbitrary two-qubit state) to Bob and Bob wants to transmit an arbitrary two-qubit state (an arbitrary single state) to Alice via the control of the supervisor Charlie.
