Journal ArticleDOI
Sideband cooling of micromechanical motion to the quantum ground state
John Teufel,Tobias Donner,Dale Li,Jennifer W. Harlow,Mark Allman,Mark Allman,Katarina Cicak,Adam Sirois,Adam Sirois,Jed D. Whittaker,Jed D. Whittaker,Konrad Lehnert,Raymond W. Simmonds +12 more
TL;DR: Sideband cooling of an approximately 10-MHz micromechanical oscillator to the quantum ground state is demonstrated and the device exhibits strong coupling, allowing coherent exchange of microwave photons and mechanical phonons.
Journal Article
Sideband cooling micromechanical motion to the quantum ground state
TL;DR: In this article, a microwave cavity optomechanical system was realized by coupling the motion of an aluminum membrane to the resonance frequency of a superconducting circuit, and damping and cooling the membrane motion with radiation pressure forces.
Journal ArticleDOI
Circuit cavity electromechanics in the strong-coupling regime
John Teufel,Dale Li,Michael S. Allman,Katarina Cicak,Adam Sirois,Jed D. Whittaker,Raymond W. Simmonds +6 more
TL;DR: The basic circuit architecture presented here provides a feasible path to ground-state cooling and subsequent coherent control and measurement of long-lived quantum states of mechanical motion and is in excellent quantitative agreement with recent theoretical predictions.
Journal ArticleDOI
Entangling Mechanical Motion with Microwave Fields
TL;DR: This result demonstrates an essential requirement for using compact and low-loss micromechanical oscillators in a quantum processor, can be extended to sense forces beyond the standard quantum limit, and may enable tests of quantum theory.
Journal ArticleDOI
Measuring nanomechanical motion with a microwave cavity interferometer
TL;DR: In this paper, the position of a nanoscale beam using a microwave cavity detector represents a promising step towards being able to measure displacements at the quantum limit, which is the goal of this paper.
