mechanical motion and its decoherence,–. Quantum control of mechanical motion has been …

Quantum control of complex objects in the regime of large size and mass provides
opportunities for sensing applications and tests of fundamental physics. The realization of …

Topological operations can achieve certain goals without requiring accurate control over
local operational details; for example, they have been used to control geometric phases and …

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 …

Quantum fluctuations of the electromagnetic vacuum produce measurable physical effects
such as Casimir forces and the Lamb shift. They also impose an observable limit—known as …

The hallmark of quantum physics is Planck's constant h, whose finite value entails the
quantization that gave the theory its name. The finite value of h gives rise to inevitable zero …

In force sensing, optomechanics, and quantum motion experiments, it is typically
advantageous to create lightweight, compliant mechanical elements with the lowest possible …
