Journal ArticleDOI
Approaching the Quantum Limit of a Nanomechanical Resonator
TL;DR: By coupling a single-electron transistor to a high-quality factor, 19.7-megahertz nanomechanical resonator, position detection approached that set by the Heisenberg uncertainty principle limit as discussed by the authors.
Journal ArticleDOI
Measurement of the quantum of thermal conductance
TL;DR: The observation of a quantized limiting value for the thermal conductance, Gth, in suspended insulating nanostructures at very low temperatures is reported, consistent with predictions for phonon transport in a ballistic, one-dimensional channel.
Journal ArticleDOI
Putting mechanics into quantum mechanics
Keith Schwab,Michael L. Roukes +1 more
TL;DR: In this article, the authors show that nanoelectromechanical structures are starting to approach the ultimate quantum mechanical limits for detecting and exciting motion at the nanoscale, and nonclassical states of a mechanical resonator are also on the horizon.
Journal ArticleDOI
Preparation and detection of a mechanical resonator near the ground state of motion
TL;DR: This work reports the cooling of the motion of a radio-frequency nanomechanical resonator by parametric coupling to a driven, microwave-frequency superconducting resonator, and expects the mechanical resonator to be found with probability 0.21 in the quantum ground state of motion.
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.
