Title:
SYNCHRONIZATION SYSTEM FOR QUANTUM NETWORKS
Document Type and Number:
WIPO Patent Application WO/2023/249655
Kind Code:
A3
Abstract:
A synchronization system for synchronizing photons in a quantum teleportation network. The synchronization system includes a multiplexer combining a clock pulse with a signal photon (carrying a qubit) in an optical fiber, the optical fiber connecting a transmitter node (including the multiplexer) and a receiver node (comprising a demultiplexer). The signal photons have signal wavelengths red shifted as compared to clock wavelengths of the clock pulses. The clock pulses have an intensity below a threshold, such that Raman scattering of the clock pulses by the fiber (shifting the clock wavelengths into the signal wavelengths) is negligible. The receiver node comprises a demultiplexer demultiplexing the one of the signal photons and the one of the clock pulses; a first detector detecting the one of the signal photons; and a second detector detecting the one of the clock pulses.
