The traditional view from particle physics is that quantum gravity effects should only become
detectable at extremely high energies and small length scales. Due to the significant …

Quantum computing is a new paradigm that will revolutionize various areas of computing,
especially cloud computing. Quantum computing, still in its infancy, is a costly technology …

We recently showed that if a massive (or charged) body is put in a quantum spatial
superposition, the mere presence of a black hole in its vicinity will eventually decohere the …

When gravity is sourced by a quantum system, there is tension between its role as the
mediator of a fundamental interaction, which is expected to acquire nonclassical features …

Atom interferometers measure quantum interference patterns in the wave functions of cold
atoms that follow superpositions of different space-time trajectories. These can be sensitive …

We present results from exploratory studies, supported by the Physics Beyond Colliders
(PBC) Study Group, of the suitability of a CERN site and its infrastructure for hosting a …

The Einstein equivalence principle (EEP) is of crucial importance to test the foundations of
general relativity. When the particles involved in the test exhibit quantum properties, it is …

We investigate the interaction of a transmon qubit with a classical gravitational field.
Exploiting the generic phenomena of the gravitational redshift and Aharonov-Bohm phase …

The study of the gravitational field produced by a spatially nonlocal, superposed quantum
state of a massive particle is an interesting and active area of research. One outstanding …

The topic of quantum reference frames (QRFs) has attracted a great deal of attention in the
recent literature. Potentially, the correct description of such frames is important for both the …
