Optical trapping describes the interaction between light and matter to manipulate micro-
objects through momentum transfer. In the case of 3D trapping 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 …

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 quantum ground state of a massive mechanical system is a stepping stone for
investigating macroscopic quantum states and building high fidelity sensors. With the recent …

Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have
become an essential tool in several fields of physics, spectroscopy, biology …

Motional control of levitated nanoparticles relies on either autonomous feedback via a cavity
or measurement-based feedback via external forces. Recent demonstrations of the …

We experimentally realize cavity cooling of all three translational degrees of motion of a
levitated nanoparticle in vacuum. The particle is trapped by a cavity-independent optical …

A recently proposed experimental protocol for quantum gravity induced entanglement of
masses (QGEM) requires in principle realizable, but still very ambitious, set of parameters in …

Dissipation and the accompanying fluctuations are often seen as detrimental for quantum
systems since they are associated with fast relaxation and loss of phase coherence …

Quantum control of a system requires the manipulation of quantum states faster than any
decoherence rate. For mesoscopic systems, this has so far only been reached by few …
