If a black hole starts in a pure quantum state and evaporates completely by a unitary
process, the von Neumann entropy of the Hawking radiation initially increases and then …

Recently, table-top experiments involving massive quantum systems have been proposed to
test the interface of quantum theory and gravity. In particular, the crucial point of the debate …

The effort to discover a quantum theory of gravity is motivated by the need to reconcile the
incompatibility between quantum theory and general relativity. Here, we present an …

We present a new characterization of quantum theory in terms of simple physical principles
that is different from previous ones in two important respects: first, it only refers to properties …

The foundations of Quantum Mechanics are experiencing a golden age. In a timespan of
less than two decades, an astonishing number of new results, ideas, and frameworks have …

Entanglement is one of the most striking features of quantum mechanics, and yet it is not
specifically quantum. More specific to quantum mechanics is the connection between …

Despite its enormous empirical success, the formalism of quantum theory still raises
fundamental questions: why is nature described in terms of complex Hilbert spaces, and …

As first noted by Rafael Sorkin, there is a limit to quantum interference. The interference
pattern formed in a multi-slit experiment is a function of the interference patterns formed …

The effort to discover a quantum theory of gravity is motivated by the need to reconcile the
incompatibility between quantum theory and general relativity. Here, we present an …

In this note we lay some groundwork for the resource theory of thermodynamics in general
probabilistic theories (GPTs). We consider theories satisfying a purely convex abstraction of …
