kvantsidekanalid
Kvantsidekanalid are channels of information leakage that arise from unintended couplings between a quantum system and its environment or from imperfections in quantum devices. They can reveal information about quantum states, keys, or computations without breaking the protocol's formal security assumptions. They are a concern in quantum cryptography, computation, and metrology.
They take various forms, including timing information, power draw, electromagnetic or optical emissions, thermal signatures, and
In quantum key distribution (QKD), common side channels include multi-photon emissions enabling photon-number splitting, detector vulnerabilities
In quantum computing, side channels may arise from control lines, power supplies, or thermal fluctuations that
Defensive approaches include device-independent or measurement-device-independent QKD to reduce hardware trust, decoy-state methods to limit information
The study of kvantsidekanalid is part of broader quantum security and engineering practice, reflecting the need
