  - <jats:p>Modulation conditioned on measurements on entangled photonic quantum states
    is a cornerstone technology of optical quantum information processing. Performing
    this task with low latency requires combining single-photon-level detectors with
    both electronic logic processing and optical modulation in close proximity. Here,
    we demonstrate low-latency feedforward using a quasi-photon-number-resolved measurement
    on a quantum light source. Specifically, we use a multipixel superconducting nanowire
    single-photon detector, amplifier, logic, and an integrated electro-optic modulator
    <jats:italic toggle="yes">in situ</jats:italic> below 4 K. We modulate the signal
    mode of a spontaneous parametric down-conversion source, conditional on a photon-number
    measurement of the idler mode, with a total latency of (23±3)ns. Furthermore,
    we investigate the resulting change in the photon statistics. This represents
    an important benchmark for the fastest quantum photonic feedforward experiments
    comprising measurement, amplification, logic, and modulation. This has direct
    applications in quantum computing, communication, and simulation protocols.</jats:p>@eng
