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 ArticleDOI
Decoherence in Josephson qubits from dielectric loss.
John M. Martinis,Ken Cooper,Robert McDermott,Matthias Steffen,Markus Ansmann,Kevin Osborn,Katarina Cicak,Seongshik Oh,David P. Pappas,Raymond W. Simmonds,Clare C. Yu +10 more
TL;DR: In this paper, the authors show that a variety of microwave and qubit measurements are well modeled by loss from resonant absorption of two-level defects and demonstrate that this loss can be significantly reduced by using better dielectrics and fabricating junctions of small area.
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
Bidirectional and efficient conversion between microwave and optical light
R. W. Andrews,R. W. Peterson,T. P. Purdy,Katarina Cicak,Raymond W. Simmonds,Cindy Regal,Konrad Lehnert,Konrad Lehnert +7 more
TL;DR: In this paper, an optomechanical system that converts microwaves to optical frequency light and vice versa is demonstrated, achieving a conversion efficiency of approximately 10% in terms of energy consumption.
Proceedings ArticleDOI
Bidirectional and efficient conversion between microwave and optical light
Cindy Regal,R. W. Andrews,R. W. Peterson,T. P. Purdy,Katarina Cicak,Raymond W. Simmonds,Konrad Lehnert +6 more
TL;DR: In this article, the authors demonstrate efficient mechanically-mediated transduction between microwave and optical signals using a micromechanical SiN membrane, which has the potential to transform information between these vastly different frequencies while maintaining a fragile quantum state.
