Quantum decoherence plays a pivotal role in the dynamical description of the quantum-to-
classical transition and is the main impediment to the realization of devices for quantum …

The superposition principle is the cornerstone of quantum mechanics, leading to a variety of
genuinely quantum effects. Whether the principle applies also to macroscopic systems or …

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 …

This paper points out the importance of the assumption of locality of physical interactions,
and the concomitant necessity of propagation of an entity (in this case, off-shell quanta …

'Der Kopf, so gesehen, hat mit dem Kopf, so gesehen, auch nicht die leiseste Ahnlichkeit (...)
Der Aspektwechsel.“Du würdest doch sagen, dass sich das Bild jetzt gänzlich geändert hat!” …

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 …

This book has been developed from an account of three lectures I gave at Princeton
University in October 2003 at the invitation of Princeton University Press. The title I had …

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 …

Quantum technologies are opening novel avenues for applied and fundamental science at
an impressive pace. In this perspective article, we focus on the promises coming from the …

Levitated optomechanics, a new experimental physics platform, holds promise for
fundamental science and quantum technological sensing applications. We demonstrate a …
