Mechanical resonators are widely used in sensors, transducers and optomechanical
systems, where mechanical dissipation sets the ultimate limit to performance. Over the past …

The field of nanoscale magnetic resonance imaging (NanoMRI) was started 30 years ago. It
was motivated by the desire to image single molecules and molecular assemblies, such as …

Systems with low mechanical dissipation are extensively used in precision measurements
such as gravitational wave detection, atomic force microscopy, and quantum control of …

Cavity electromechanics relies on parametric coupling between microwave and mechanical
modes to manipulate the mechanical quantum state, and provide a coherent interface …

At room temperature, mechanical motion driven by the quantum backaction of light has been
observed only in pioneering experiments in which an optical restoring force controls the …

We report the development of a scanning force microscope based on an ultrasensitive
silicon nitride membrane optomechanical transducer. Our development is made possible by …

Many protocols in quantum science and technology require initializing a system in a pure
quantum state. In the context of the motional state of massive resonators, this enables …

The new generation of strained-silicon-nitride resonators harbors great promise for scanning
force microscopy, especially when combined with the extensive toolbox of cavity …

Dissipation dilution enables extremely low linear loss in stressed, high aspect ratio
nanomechanical resonators, such as strings or membranes. Here, we report on the …

We demonstrate that soft-clamped silicon nitride strings with a large aspect ratio can be
operated at mK temperatures. The quality factors (Q) of two measured devices show …
