1. A method, comprising:
generating carrier qubits comprising quantum superposition states by at least expanding first basis sets of encoding qubits encoding payload data to carrier qubits having second basis sets expanded from the encoding qubits;
generating a transmission signal by at least projecting the carrier qubits onto a physical carrier comprising an adjustable multiplexing scheme;
selecting the adjustable multiplexing scheme based at least on communication medium conditions and a desired information capacity of the transmission signal by at least selecting a multiplexing degree and a multiplexing type from one or more among a spectral multiplexing scheme comprising a selected quantity of non-overlapping frequencies and a spatial multiplexing scheme comprising a selected quantity of optical vortex states; and
transmitting, by the physical carrier, the transmission signal through a communication medium.
