Quantum theory has been successfully validated in numerous laboratory experiments. But
would such a theory, which effectively describes the behavior of microscopic physical …

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 …

Since the first proof-of-principle experiments over 25 years ago, atom interferometry has
matured to a versatile tool that can be used in fundamental research in particle physics …

Quantum mechanics governs the microscopic world, where low mass and momentum reveal
a natural wave–particle duality. Magnifying quantum behaviour to macroscopic scales is a …

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 …

Owing to the low-gravity conditions in space, space-borne laboratories enable experiments
with extended free-fall times. Because Bose–Einstein condensates have an extremely low …

Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

Substantial leaps in the understanding of quantum systems have been driven by exploring
geometry, topology, dimensionality and interactions in ultracold atomic ensembles,,,,–. A …

We propose in this White Paper a concept for a space experiment using cold atoms to
search for ultra-light dark matter, and to detect gravitational waves in the frequency range …

Deployment of ultracold atom interferometers (AI) into space will capitalize on quantum
advantages and the extended freefall of persistent microgravity to provide high-precision …
