Abstract

In this paper, we propose a protocol of joint remote state preparation of an equatorial two-qubit pure quantum state using GHZ states, performing projective measurements and appropriate unitary operations. The probability of success of our scheme is shown to increase if one of the parties holding the partial information transmits the information classically to the receiver.

Keywords

Joint remote state preparation Equatorial two-qubit state  Projective measurement Unitary operation
