Cryogenic Feedforward of a Quantum State

Key Points

• Low-latency feedforward is achieved by operating key processes at cryogenic temperatures, enhancing performance.
• Using quasi photon-number resolving SNSPDs, the system effectively detects and processes photons with minimal delay.
• Electro-optic modulation and in-situ logic processing contribute significantly to the system's low processing delays.
• This approach indicates potential breakthroughs in quantum computing and photonic systems, creating faster interactions.
