A method and a system for generating a hyper-entangled high-dimensional time-bin frequency-bin state, the method comprising generating a hyper-entangled state composed of a time-bin and frequency-bin encoded state, and individually modifying at least one of: i) the amplitude and ii) the phase of the state components at different frequency-bins and different time-bins of the hyper-entangled state. The system comprises a non-linear medium exited with multiple pulses in broad phase-matching conditions, a frequency mode separator and an amplitude/phase modulator, the frequency mode separator temporally and spatially separating frequency modes of the hyper-entangled state, the amplitude/phase modulator individually modifying at least one of: i) the amplitude (and ii) the phase of the state components at different frequency-bins and different time-bins of the hyper-entangled state.

Method and system for generation and control of high-dimensional multi-partite quantum states

A system and a method for phase extraction of a multi-path interferometer, the method comprising generating a reference signal of a coherence length longer than an arm length difference of the multi-path interferometer; splitting the reference signal into a frequency shifted reference signal and an unshifted reference signal; recombining the frequency shifted reference signal and the unshifted reference signal into a polarization- and frequency-multiplexed reference signal, and feeding the polarization- and frequency-multiplexed reference signal to the multi-path interferometer; detecting frequency shifted and unshifted output signals of the multi-path interferometer; and determining the interferometer phase from the detected signal.
