Quantum optical measurement techniques offer a rich avenue for quantum control of mechanical oscillators via cavity optomechanics. In particular, a powerful yet little explored combination utilizes optical measurements to perform heralded non-Gaussian mechanical state preparation followed by tomography to determine the mechanical phase-space distribution. Here, we experimentally perform heralded single-phonon and multiphonon subtraction via photon counting to a laser-cooled mechanical thermal…

Nano-acoustic resonator with ultralong phonon lifetime
Measurements of the phonon lifetime of a microwave-frequency, nanoscale silicon acoustic cavity incorporating a phononic bandgap acoustic shield are presented, providing a window into the material origins of quantum noise.
Superconducting qubit to optical photon transduction.
This work demonstrates the conversion of a microwave-frequency excitation of a transmon-a type of superconducting qubit-into an optical photon by using an intermediary nanomechanical resonator that converts the electricalexcitation of the qubit into a single phonon by means of a piezoelectric interaction and subsequently converts the phonon to an optical photons by Means of radiation pressure.
Encoding a qubit in a trapped-ion mechanical oscillator
A single logical qubit is encoded, manipulated and read out using a superposition of displaced squeezed states of the harmonic motion of a trapped calcium ion, which opens a route for exploring continuous variable error correction as well as hybrid quantum information schemes using both discrete and continuous variables.
