Abstract
The present disclosure is directed to a system and method of distributing time information to enable synchronization in an authenticated manner via a quantum channel. A source device may transmit a timing signal, T on a communication channel from the source device to a receiver device. The timing signal T may be include a time or times stored in memory or calculated using a previously agreed upon formula. The method may include transmitting a quantum system Q from the source device to the receiver device. The quantum system may be prepared in a randomly chosen state and may be measured by the receiver device in a randomly chosen measurement basis.
