Asymmetric Controlled Bidirectional Remote Preparation of Single- and Three-Qubit Equatorial State in Noisy Environment
We present an asymmetric controlled bidirectional remote Handsoap preparation scheme under the control of Charlie, where Alice transmits an arbitrary single-qubit equatorial state to Bob and Bob transmits an arbitrary three-qubit equatorial state to Alice.First, the quantum channel is constructed by using Hadamard ( ${H}$ ) and CNOT operations.Seco
