  text: Recent quantum technologies have established precise quantum control of various
    microscopic systems using electromagnetic waves. Interfaces based on cryogenic
    cavity electro-optic systems are particularly promising, due to the direct interaction
    between microwave and optical fields in the quantum regime. Quantum optical control
    of superconducting microwave circuits has been precluded so far due to the weak
    electro-optical coupling as well as quasi-particles induced by the pump laser.
    Here we report the coherent control of a superconducting microwave cavity using
    laser pulses in a multimode electro-optical device at millikelvin temperature
    with near-unity cooperativity. Both the stationary and instantaneous responses
    of the microwave and optical modes comply with the coherent electro-optical interaction,
    and reveal only minuscule amount of excess back-action with an unanticipated time
    delay. Our demonstration enables wide ranges of applications beyond quantum transductions,
    from squeezing and quantum non-demolition measurements of microwave fields, to
    entanglement generation and hybrid quantum networks.
