Optical trap** describes the interaction between light and matter to manipulate micro-
objects through momentum transfer. In the case of 3D trap** with a single beam, this is …

BACKGROUND Levitation of large objects has become a widely used technique in science
and engineering, and the control of levitated nano-and micro-objects in vacuum has gained …

Tests of quantum mechanics on a macroscopic scale require extreme control over
mechanical motion and its decoherence,–. Quantum control of mechanical motion has been …

The ability to accurately control the dynamics of physical systems by measurement and
feedback is a pillar of modern engineering. Today, the increasing demand for applied …

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 …

The first direct measurement of gravitational waves by the LIGO and Virgo collaborations
has opened up new avenues to explore our Universe. This white paper outlines the …

Controlling a quantum system by using observations of its dynamics is complicated by the
backaction of the measurement process—that is, the unavoidable quantum disturbance …

Optomechanics is concerned with the use of light to control mechanical objects. As a field, it
has been hugely successful in the production of precise and novel sensors, the …

We report on rotating an optically trapped silica nanoparticle in vacuum by transferring spin
angular momentum of light to the particle's mechanical angular momentum. At sufficiently …

The small mass and high coherence of nanomechanical resonators render them the ultimate
mechanical probe, with applications that range from protein mass spectrometry and …
