Concerted efforts are underway to establish an infrastructure for a global quantum Internet to
realise a spectrum of quantum technologies. This will enable more precise sensors, secure …

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 …

The emergence of quantum mechanics and general relativity has transformed our
understanding of the natural world significantly. However, integrating these two theories …

Observable signatures of the quantum nature of gravity at low energies have recently
emerged as a promising new research field. One prominent avenue is to test for …

Satellite-based quantum communication (QC) is an invaluable resource for the realization of
a quantum network at the global scale. In this regard, the use of satellites well beyond the …

Both quantum mechanics and general relativity are based on principles that defy our daily
intuitions, such as time dilation, quantum interference and entanglement. Because the …

Abstract The National Aeronautics and Space Administration's Deep Space Quantum Link
mission concept enables a unique set of science experiments by establishing robust …

Quantum mechanics and general relativity have been each successfully tested in numerous
experiments. However, the regime where both theories are jointly required to explain …

Ultracold neutrons are great experimental tools to explore the gravitational interaction in the
regime of quantized states. From a theoretical perspective, starting from a Dirac equation in …

We propose an approach that allows to systematically take into account gravity in quantum
particle physics. It is based on quantum field theory and the general principle of relativity …
