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 …

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 …

We describe a variety of searches for new physics beyond the standard model of particle
physics which may be enabled in the coming years by the use of optically levitated masses …

The experimental observation of a clear quantum signature of gravity is believed to be out of
the grasp of current technology. However, several recent promising proposals to test the …

Advances in quantum technologies are giving rise to a revolution in the way fundamental
physics questions are explored at the empirical level. At the same time, they are the seeds …

The Majorana Demonstrator neutrinoless double-beta decay experiment comprises a 44 kg
(30 kg enriched in Ge 76) array of p-type, point-contact germanium detectors. With its …

Quantum theory is incredibly successful, explaining the microscopic world with great
accuracy, from the behaviour of subatomic particles to chemical reactions to solid-state …

Abstract Space-based research can provide a major leap forward in the study of key open
questions in the fundamental physics domain. They include the validity of Einstein's …

Noninterferometric experiments have been successfully employed to constrain models of
spontaneous wave function collapse, which predict a violation of the quantum superposition …

Controlling the motion of macroscopic oscillators in the quantum regime has been the
subject of intense research in recent decades. In this direction, opto-mechanical systems …
