利用六量子比特团簇态作为量子信道，研究了任意赤道两量子比特态的联合远程态制备。在振幅阻尼噪声和相位阻尼噪声等噪声环境中，我们解析地得到了联合遥态制备过程的稳定性。在我们的方案中，振幅阻尼噪声和相位阻尼噪声这两种不同的噪声只影响量子信道中的旅行量子比特，然后我们证明了在这两种噪声情况下的相干性只依赖于退相干噪声率.
By using a six-qubit cluster state as the quantum channel, we investigat the joint remote state preparation of an arbitrary equatorial two-qubit state. We analytically obtain the fidelities of the joint remote state preparation process in noisy environments, such as the amplitude-damping noise and phase-damping noise. In our scheme, the two different noise including amplitude-damping noise and the phase-damping noise only affect the travel qubits of the quantum channel, and then we show that the fidelities in these two noisy cases only depend on the decoherence noisy rate.
