量子通信是量子反事实通信吗?

How Quantum is Quantum Counterfactual Communication?

Jonte R. Hance, James Ladyman, John Rarity

摘要:

量子反事实通信是最近提出的使用量子物理在双方之间发送消息的想法,而没有任何与发送的比特相关的物质/能量转移。虽然这激发了巨大的兴趣,无论是对潜在的“不可破解”的通信,还是对量子力学基础的洞察,但人们一直在问这个过程本质上是量子的,还是可以经典地进行。我们研究反事实通信,经典和量子,并表明,迄今为止提出的协议发送信号,不涉及与发送的比特相关的物质/能量转移必须是量子的,因为它们需要波粒二象性。

英文摘要:

Quantum Counterfactual Communication is the recently-proposed idea of using quantum physics to send messages between two parties, without any matter/energy transfer associated with the bits sent. While this has excited massive interest, both for potential `unhackable' communication, and insight into the foundations of quantum mechanics, it has been asked whether this process is essentially quantum, or could be performed classically. We examine counterfactual communication, both classical and quantum, and show that the protocols proposed so far for sending signals that don't involve matter/energy transfer associated with the bits sent must be quantum, insofar as they require wave-particle duality.
