• Abstract: Quantum key distribution (QKD) enables secure key sharing between distant parties, with several protocols proven resilient against conventional eavesdropping strategies. Here, we introduce a new attack scenario where an eavesdropper, Eve, exploits a quantum switch using the indefinite causal order to intercept and manipulate quantum communication channel. Using multiple metrics such as the information gain, mutual information, and Bell violation, we demonstrate that the presence of a quantum switch significantly compromises QKD security. Our results highlight a previously overlooked vulnerability, emphasizing the need for countermeasures against quantum-controlled adversarial strategies.

  Quantum key distribution (QKD) can generate secure key bits between remote users with quantum mechanics. The most insidious attacks, known as quantum hacking, are the ones with no significant discrepancy of the measurement results. We propose the method exploring temporal ghost imaging (TGI) scheme to perceive quantum hacking with temporal fingerprints.
