Abstract
The capacity of quantum states to send information is a fundamental and intriguing issue in quantum communication theory. This study explores a scenario where Alice intends to transmit n bits of classical information to Bob by sending m qudits, using an arbitrary bipartite pure entangled state with E qudits as the shared resource. We employ the unambiguous discrimination strategy in decoding and establish an upper bound on the success probability, which extends the findings of a previous study (Li in Phys Rev A 85:052304, 2012).
量子态发送信息的能力是量子通信理论中一个基本而有趣的问题。本研究探讨了一种场景，其中Alice打算通过发送m个qudits向Bob传输n位经典信息，使用任意二部纯纠缠态，其中E个qudits作为共享资源。我们在解码中采用了无二义辨别策略，并建立了成功概率的上界，这扩展了先前研究的结果（Li in Phys Rev a 85:052304, 2012）。
