OPTICALLY MULTIPLEXED QUANTUM CONTROL

A qubit control system for a quantum computer includes a source of a plurality optical carriers; an optical modulator to receive the plurality optical carriers and to modulate each optical carrier with a qubit control signal to provide a plurality of modulated optical signals; an optical multiplexer to provide a wavelength division multiplexed optical signal; an optical waveguide to receive and transmit the wavelength division multiplexed optical signal therethrough; an optical demultiplexer to receive the wavelength division multiplexed optical signal to recover each of the plurality of modulated optical signals; a demodulator to receive each of the recovered plurality of modulated optical signals to output a corresponding plurality of recovered qubit control signals to control subsets of a plurality of qubits.
