论文摘要
在本文中，我们对概率量子通信协议进行了重新研究，并开发了一种非传统的远程状态准备协议，该协议允许使用非最大值纠缠的通道确定性地传输在量子状态中编码的信息。使用辅助粒子和简单的测量方法，准备D维量子状态的成功概率将增加到1，而无需事先花费额外的量子资源以改善量子通道，例如纠缠纯化。此外，我们设计了一种可行的实验方案，以证明使用广义纠缠状态将极化编码的光子从一个位置转移到另一个位置的确定性范例。这种方法提供了一种实用的方法，可以解决实际量子通信中的破坏性和环境噪声。
In this paper, we have reinvestigated probabilistic quantum communication protocols and developed a nontraditional remote state preparation protocol that allows for deterministically transferring information encoded in quantum states using a non-maximally entangled channel. With an auxiliary particle and a simple measurement method, the success probability of preparing a d-dimensional quantum state is increased to 1 without spending additional quantum resources in advance to improve quantum channels, such as entanglement purification. Furthermore, we have designed a feasible experimental scheme to demonstrate the deterministic paradigm of transporting a polarization-encoded photon from one location to another using a generalized entangled state. This approach provides a practical method to address decoherence and environmental noises in actual quantum communication.
