Quantum Spread Spectrum Multiple Access
Juan Carlos García-Escartín, Pedro Chamorro‐Posada · IEEE Journal of Selected Topics in Quantum Electronics · 2014
We describe a quantum multiple access scheme that can take separate single photon channels and combine them in the same path. We propose an add-drop multiplexer that can insert or extract a single photon into an optical fiber carrying the qubits of all the other users. The system follows the principle of code division multiple access, a spread spectrum technique widely used in cellular networks.
