We introduce the framework of general probabilistic theories (GPTs for short). GPTs are a
class of operational theories that generalize both finite-dimensional classical and quantum …

Building on work by Tsirelson, we present a family of protocols that detect the nonclassicality
of suitable states of a single quantum system, under the sole assumption that the measured …

We consider how to describe Hamiltonian mechanics in generalized probabilistic theories
with the states represented as quasiprobability distributions. We give general operational …

Hamiltonian mechanics describes the evolution of a system through its Hamiltonian. The
Hamiltonian typically also represents the energy observable, a Noether-conserved quantity …

We show that the phase-space formulation of general probabilistic theories can be extended
to include a generalized time evolution and that it can describe a nonquantum hydrogenlike …

We develop the theory of Wigner representations for general probabilistic theories (GPTs), a
large class of operational theories that include both classical and quantum theory. The …

We consider a foundational question in energy harvesting: Given a partly random energy
source, is it possible to extract the energy without also transferring randomness or accepting …

In quantum mechanics, the time evolution of particles is given by the Schr\" odinger
equation. It is valid in a nonrelativistic regime where the interactions with the particle can be …

We consider a foundational question in energy harvesting: given a partly random energy
source, is it possible to extract the energy without also transferring randomness or accepting …

Information-theoretic insights have proven fruitful in many areas of quantum physics. But can
the fundamental dynamics of quantum systems be derived from purely information-theoretic …
