Journal ArticleDOI
Quantum squeezing of motion in a mechanical resonator
Emma E. Wollman,Chan U Lei,A. J. Weinstein,Junho Suh,Andreas Kronwald,Florian Marquardt,Aashish A. Clerk,Keith Schwab +7 more
TL;DR: Using microwave frequency radiation pressure, this article manipulated the thermal fluctuations of a micrometer-scale mechanical resonator to produce a stationary quadrature-squeezed state with a minimum variance of 0.80 times that of the ground state.
Journal ArticleDOI

TL;DR: In this paper, the authors investigated the detection latency of superconducting nanowire single-photon detectors (SNSPDs) and showed that the key to achieving low timing jitter is the use of materials with low latency.
Journal ArticleDOI
Mechanically Detecting and Avoiding the Quantum Fluctuations of a Microwave Field
Junho Suh,A. J. Weinstein,Chan U Lei,Emma E. Wollman,Steven Steinke,Steven Steinke,Pierre Meystre,Aashish A. Clerk,Keith Schwab +8 more
TL;DR: In this article, a two-tone back-action evading measurement with a superconducting electromechanical device is presented, which achieves the detection of backaction forces due to the quantum noise of a microwave field, and measurement imprecision of a single quadrature of motion 2.4 ± 0.4 dB.
Journal ArticleDOI
Kilopixel array of superconducting nanowire single-photon detectors.
Emma E. Wollman,Varun B. Verma,Adriana E. Lita,William H. Farr,Matthew D. Shaw,Richard P. Mirin,Sae Woo Nam +6 more
TL;DR: A 1024-element near-infrared imaging array of superconducting nanowire single photon detectors (SNSPDs) using a 32×32 row-column multiplexing architecture is presented, making it the largest SNSPD array reported to date in terms of both active area and pixel count.
Journal ArticleDOI
Quantum Nondemolition Measurement of a Quantum Squeezed State Beyond the 3 dB Limit.
Chan U Lei,A. J. Weinstein,Junho Suh,Emma E. Wollman,Andreas Kronwald,Andreas Kronwald,Florian Marquardt,Florian Marquardt,Aashish A. Clerk,Keith Schwab +9 more
TL;DR: A reservoir engineering technique based on two-tone driving is used to generate and stabilize a quantum squeezed state of a micron-scale mechanical oscillator in a microwave optomechanical system, revealing evidence for an additional mechanical parametric effect.
