- Quantum Information Processing - Year 2025
We present how the mechanisms of quantum Darwinism allow for information leakage in the standard BB84 quantum key distribution protocol, a paradigmatic prepare-and-measure quantum cryptography scenario. We work within the decoherence theory framework and employ the model of measurements provided by quantum Darwinism. We investigate how much of the information about the results crucial for the cryptographic key to be kept secret...
