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 …

Understanding gravity in the framework of quantum mechanics is one of the great
challenges in modern physics. However, the lack of empirical evidence has lead to a debate …

We discuss effects of loss of coherence in low energy quantum systems caused by or related
to gravitation, referred to as gravitational decoherence. These effects, resulting from random …

The Stern-Gerlach effect, found a century ago, has become a paradigm of quantum
mechanics. Unexpectedly, until recently, there has been little evidence that the original …

We introduce and theoretically analyze a scheme to prepare and detect non-Gaussian
quantum states of an optically levitated particle via the interaction with light pulses that …

Rotations of microscale rigid bodies exhibit pronounced quantum phenomena that do not
exist for their centre-of-mass motion. By levitating nanoparticles in ultra-high vacuum …

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 …

Gravity's quantum nature can be probed in a laboratory by witnessing the entanglement
between the two quantum systems, which cannot be possible if gravity is a classical entity. In …

We demonstrate a new mechanical transduction platform for individual spin qubits. In our
approach, single micromagnets are trapped using a type-II superconductor in proximity of …
