In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

The field of cavity optomechanics is reviewed. This field explores the interaction between
electromagnetic radiation and nanomechanical or micromechanical motion. This review …

According to quantum mechanics, a harmonic oscillator can never be completely at rest.
Even in the ground state, its position will always have fluctuations, called the zero-point …

Numerous astrophysical and cosmological observations are best explained by the existence
of dark matter, a mass density which interacts only very weakly with visible, baryonic matter …

A pair of conjugate observables, such as the quadrature amplitudes of harmonic motion,
have fundamental fluctuations that are bound by the Heisenberg uncertainty relation …

Quantum mechanics dictates that the precision of physical measurements must always
comply with certain noise constraints. In the case of interferometric displacement …

The QCD axion is one of the most compelling candidates to explain the dark matter
abundance of the Universe. With its extremely small mass (≪ 1 eV/c 2), axion dark matter …

The topic of quantum noise has become extremely timely due to the rise of quantum
information physics and the resulting interchange of ideas between the condensed matter …

By coupling a macroscopic mechanical oscillator to two microwave cavities, we
simultaneously prepare and monitor a nonclassical steady state of mechanical motion. In …

Achieving coherent quantum control over massive mechanical resonators is a current
research goal. Nano-and micromechanical devices can be coupled to a variety of systems …
