Controlled cyclic joint remote state preparation of arbitrary single-qubit states

A novel scheme for controlled cyclic joint remote state preparation (CCJRSP) is proposed where arbitrary single-qubit state can be mutually transmitted between three communication participants Alice, Bob and Charlie under the control of the supervisor David. In our scheme, one participant can reconstruct the desired states by performing POVM measurement and basic unitary transformation with the help of other two participants in a cyclic manner. In addition, one non-maximally entangled channel is utilized in this work. Hence, the requirement for the quantum channel is reduced.
