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 …

Nanomechanics has brought mesoscopic physics into the world of vibrations. Because
nanomechanical systems are small, fluctuations are significant, the vibrations already …

Coherent tripartite interactions among degrees of freedom of completely different nature are
instrumental for quantum information and simulation technologies, but they are generally …

We extend the concept of dynamical decoupling from spin to mechanical degrees of
freedom of macroscopic objects, for application in interferometry. In this manner, 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 …

Nanodiamonds containing negatively charged nitrogen vacancy centers (NV−) have
applications as localized sensors in biological materials and have been proposed as a …

Observing and controlling macroscopic quantum systems has long been a driving force in
quantum physics research. In particular, strong coupling between individual quantum …

We use an optimal control protocol to cool one mode of the center-of-mass motion of an
optically levitated nanoparticle. The feedback technique relies on exerting a Coulomb force …

Levitated diamond particles in high vacuum with internal spin qubits have been proposed for
exploring macroscopic quantum mechanics, quantum gravity, and precision measurements …

We spatially expand and subsequently contract the motional thermal state of a levitated
nanoparticle using a hybrid trapping scheme. The particle's center-of-mass motion is …
