Most proposals to witness the quantum nature of gravity in the low-energy regime rely on the Newtonian potential: a c-independent interaction that survives the c → ∞ limit and therefore carries no direct imprint of the relativistic structure of…

We adapt to the context of quantum theory the treatment, familiar in relativity theory, of a reference frame as a tetrad.

The Gaussian formalism of continuous variables (CV), first developed in quantum optics, offers an operational and analytical framework suitable for theoretical analysis and experimental modelling of levitated systems.

The lecture presents a unification of classical and quantum mechanics in terms of signal processing.

Real measurement devices are never perfect — they misidentify particles and resolve only a fraction of the system. I present a unified picture of what happens to a many-body quantum system when probed through such imperfect detectors.

The standard description of the Aharonov-Bohm (AB) effect relies on the topological phase shift, which leaves the precise spacetime location of the interaction unspecified and introduces apparent nonlocality into quantum mechanics.

Can high-energy quantum fluctuations leave an imprint at low energies?

Coherent control of quantum channels refers to the possibility of applying different channels, acting on a particle’s internal degree of freedom, depending on its path degree of freedom, which can be in a coherent superposition.

A dynamics-based test, originally proposed by Tsirelson for the harmonic oscillator, provides a method for certifying quantumness under the assumption of a known Hamiltonian.

The nascent field of levitated optomechanics or levitodynamics has set itself on the quest to realise matter-wave interferometry with a 'massive' mesoscopic solid. Creating, manipulating and observing such a macroscopic spatial superposition has the…
