Abstract

Quantum data locking (QDL), proposed as a conceptually different alternative to quantum key distribution, uses a small secret key to lock a much longer message for secure transmission. For practical use, QDL must be robust against noise. Theorists lay the necessary theoretical ground for development of QDL protocols using noisy quantum channels.
