On defining the Hamiltonian beyond quantum theory

ODO. DahlstenDBAG Foundations of Physics

A Hamiltonian recipe

An explicit recipe for defining the Hamiltonian in general probabilistic theories, which have the potential to generalise quantum theory.

Maximum one-shot dissipated work from Rényi divergences

One-shot statistic

One-shot analogs of fluctuation-theorem results help unify these two approaches for small-scale, nonequilibrium statistical physics.

Quantum generalisation of feedforward neural networks

ODO. DahlstenKWHKRGMK Nature Quantum Information

Quantum neural networks

We generalise neural networks into a quantum framework, demonstrating the possibility of quantum auto-encoders and teleportation.

ODO. DahlstenCBTFVV Proceedings of the Royal Society A

Quantum thermodynamics

Spectroscopy experiments show that energy shifts due to photon emission from individual molecules satisfy a fundamental quantum relation.
