• Abstract: We present an optical quantum random number generator based on vacuum fluctuation measurements that uses multi-mode coherent states generated by electro-optical phase modulation of an intense optical carrier. In this approach the weak coherent multi-mode state (or a vacuum state) interferes with the carrier, which acts as a local oscillator, on each side mode independently. The proposed setup can effectively compensate for deviations between the two arms of a balanced detector by controlling the modulation index of the electro-optical phase modulator. We perform a proof-of-principle experiment and demonstrate random number generation with a possibility of real-time randomness extraction at the rate of 400 Mbit/s.

  We experimentally build a quantum random number generator from homodyne measurements on the quadrature of the vacuum fluctuations. Semi-device-independence in this random number generator is usually obtained using phase modulators to shift the phase of the laser. We characterize the experimental parameters for optimal performance of this source-device independent quantum random number generator.

• Chaos with Gaussian invariant distribution by quantum-noise random phase feedback [5.604987100566532]
  The quantum noise from vacuum fluctuations is acquired by balanced homodyne detection and injected into a phase modulator to form a random phase feedback. By the quantum-noise random phase feedback, the transient intensity distributions of the chaotic outputs are improved. The chaotic time-delay signature and mean permutation entropy are suppressed to 0.036 and enhanced to 0.999 using the random phase feedback.
