The QP³ Lab builds piezo-optomechanical integrated circuits that couple photons, phonons, and electric fields — enabling new tools for quantum computing, networking, signal processing, and precision sensing.
Everything we build starts from the same idea: piezoelectricity lets electrical signals talk to mechanical motion, and mechanical motion talks to light. From that coupling we build circuits, processors, and sensors.
Photonic integrated circuits that generate, route, and modulate light for quantum information — with piezo-optomechanics providing low-power, cryo-compatible control.
Chip-scale beam delivery, switching, and modulation for atomic qubits. Piezo-actuated photonics provides fast, low-power optical control that scales to the thousands of channels trapped-atom and trapped-ion processors will demand.
Heterogeneous integration of diamond color centers with piezo-optomechanical circuits, linking long-lived spin qubits to photons and phonons for on-chip quantum memories, repeaters, and transducers.
Frequency combs, wavelength conversion, and squeezed light in low-loss nonlinear waveguides — the photonic toolbox that connects our devices to qubits, clocks, and telecom fiber.
Sound at gigahertz frequencies, guided and amplified on a chip. Phonons are slow, compact, and couple to nearly everything — we make them active circuit elements rather than passive delay lines.
Drifting electrons in a semiconductor can amplify a co-propagating acoustic wave and attenuate the reverse one. We use this acoustoelectric effect to build phononic amplifiers, isolators, and circulators with gain — components RF acoustics has never had.
Operating phononic circuits in the quantum regime: single-phonon sources, phononic waveguides and resonators coupled to qubits, and mechanical modes as compact quantum memories and interconnects.
When photons and phonons share a waveguide — and acoustoelectric gain removes the acoustic loss — entirely new classes of chip-scale RF-photonic processors become possible.
Acousto-optic modulation is powerful but lossy; acoustoelectric gain flips the sign. By amplifying the acoustic wave as it scatters light, we realize traveling-wave amplification and low-power modulation in a single hybrid device.
A self-sustaining oscillator in which optical and acoustic waves regenerate each other with acoustoelectric gain closing the loop — a route to ultra-low phase noise microwave generation on a photonic chip.
Optomechanical transduction turns tiny forces, fields, and photons into measurable optical signals — with sensitivity that approaches, and is calibrated by, fundamental quantum limits.
Accelerometers and gyroscopes that read out a mechanical test mass with light, delivering self-calibrated, navigation-grade inertial sensing in a chip-scale package.
Magnetostrictive materials convert magnetic fields into strain that optomechanical cavities read out with extreme precision — compact, room-temperature magnetometry without shielding.
Absorbed X-rays deposit heat and momentum in a mechanical resonator; optical readout resolves the resulting motion, opening a path to high-resolution, chip-scale X-ray detection.
Color-center spins in diamond, coupled to strain and integrated photonics, sense magnetic fields, temperature, and rotation at the nanoscale — quantum sensors built into the fabric of our devices.
