We prove the unconditional security of an entanglement-based quantum-key-distribution protocol using detectors that respond to multiple modes of light and cannot distinguish between one from two or more photons. Even with such practical detectors, any defect in the source is automatically detected as an increase in the error rate or in the rate of double clicks.

  1. Security of passive entanglement-based key distribution protocols

    quant-ph 2026-07 accept novelty 7.0

    Passive BBM92 and QCKA with biased basis choice are proven secure in the asymptotic limit, with key rates nearly identical to active protocols.
