量子反事实通信是最近提出的一种想法，即使用量子物理在双方之间发送消息，而不需要与发送的比特相关的任何物质/能量转移。虽然这激起了人们对潜在的“不可破解”的通信和对量子力学基础的洞察的巨大兴趣，但人们一直在问，这个过程本质上是量子的，还是可以经典地执行。我们研究了反事实通信，包括经典的和量子的，并表明到目前为止提出的用于发送不涉及与发送的比特相关的物质/能量转移的信号的协议必须是量子的，因为它们需要波粒二元性。
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.
