Coupling a superconducting quantum circuit to a phononic crystal defect cavity
Patricio Arrangoiz-Arriola, E. Alex Wollack, Marek Pechal +3
Connecting nanoscale mechanical resonators to microwave quantum circuits opens new avenues for storing, processing, and transmitting quantum information. In this work, we couple a…
A single-mode phononic wire
Rishi N. Patel, Zhaoyou Wang, Wentao Jiang +3
Photons and electrons transmit information to form complex systems and networks. Phonons on the other hand, the quanta of mechanical motion, are often considered only as carriers o…
Thermalization properties at mK temperatures of a nanoscale optomechanical resonator with acoustic-bandgap shield
Sean M. Meenehan, Justin D. Cohen, Simon Groeblacher +4
Optical measurements of a nanoscale silicon optomechanical crystal cavity with a mechanical resonance frequency of 3.6GHz are performed at sub-kelvin temperatures. We infer optical…
Squeezing of light via reflection from a silicon micromechanical resonator
Amir H. Safavi-Naeini, Simon Groeblacher, Jeff T. Hill +3
We present the measurement of squeezed light generation using an engineered optomechanical system fabricated from a silicon microchip and composed of a micromechanical resonator co…
Measurement of the quantum zero-point motion of a nanomechanical resonator
Amir H. Safavi-Naeini, Jasper Chan, Jeff T. Hill +3
We present optical sideband spectroscopy measurements of a mesoscopic mechanical oscillator cooled near its quantum ground state. The mechanical oscillator, corresponding to a 3.99…
Laser cooling of a nanomechanical oscillator into its quantum ground state
Jasper Chan, T. P. Mayer Alegre, Amir H. Safavi-Naeini +5
A patterned Si nanobeam is formed which supports co-localized acoustic and optical resonances that are coupled via radiation pressure. Starting from a bath temperature of T=20K, th…
