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 …

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 …

MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to
explore fundamental physics with atom interferometry over a 100 m baseline. This novel …

Matter-wave interference experiments provide a direct confirmation of the quantum
superposition principle, a hallmark of quantum theory, and thereby constrain possible …

In contrast to light, matter-wave optics of quantum gases deals with interactions even in free
space and for ensembles comprising millions of atoms. We exploit these interactions in a …

Mechanical objects have important practical applications in the fields of quantum information
and metrology as quantum memories or transducers for measuring and connecting different …

The quantum superposition principle allows massive particles to be delocalized over distant
positions. Though quantum mechanics has proved adept at describing the microscopic …

Quantum physics has intrigued scientists and philosophers alike, because it challenges our
notions of reality and locality—concepts that we have grown to rely on in our macroscopic …

Atom interferometers are powerful tools for both measurements in fundamental physics and
inertial sensing applications. Their performance, however, has been limited by the available …

In contrast to the spatial Bell's inequalities which probe entanglement between spatially
separated systems, the Leggett–Garg inequalities test the correlations of a single system …
