We show that if a massive (or charged) body is put in a quantum superposition of spatially separated states in the vicinity of a black hole or cosmological horizon, the mere presence of the horizon will eventually destroy the coherence of the…

The Quantum Technologies and Dark Matter research laboratory has a rich history of developing precision tools for both fundamental physics and industrial applications. This includes the development and application of novel low-loss and highly…

Quantum complexity is emerging as a key feature of many-body systems, including black holes, topological materials, and early quantum computers.

Optomechanical devices provide a high degree of control over the optical and mechanical degrees of freedom of their constituents. These devices are therefore particularly suitable for sensing applications but also for performing fundamental tests of…

It’s not straight-forward to adequately and uncontroversially explain, in terms of theory testing alone, the significance of difficult proposed experiments to produce and observe gravitationally induced entanglement (GIE).

In this talk, I will start by describing Einstein's original understanding of coordinate systems and how that understanding led to the hole argument and a detour in the creation of general relativity.
