  • Microwave photonic Ising machine
    Patent number: 11929788
    Abstract: Disclosed is a microwave photonic Ising machine, including: a closed loop including a phase and electro-optical conversion module and a storage, correlation and photoelectric conversion module connected in turn; a laser light source configured to generate and input an optical signal to the phase and electro-optical conversion module; and a microwave pulse local oscillator source configured to generate and input a microwave pulse signal to the phase and electro-optical conversion module. The phase and electro-optical conversion module is configured to modulate the microwave pulse signal, the optical signal, and a phase-specific two-phase microwave pulse spin electrical signal input from the storage, correlation and photoelectric conversion module to obtain and input a phase-specific two-phase microwave pulse spin optical signal to the storage, correlation and photoelectric conversion module for storage and correlation.
