When Isolated Quantum Systems Appear Classical
Thiago R. de Oliveira, Pedro S. Correia, Tiago Debarba +3
The emergence of classical behavior and the origin of thermal equilibrium are two central problems in the foundations of physics. In the standard accounts, both phenomena are typic…

Comparing Classical Simulation and Sample-Based Learning of Quantum Systems
João Pedro Del Rey, João Pedro d'El-Rey, Raúl O. Vallejos +1
We investigate the relationship between two distinct classical approaches to quantum systems: direct simulation from a classical description and sample-based learning from measurem…

A finite-resources description of a measurement process and its implications for the "Wigner's Friend" scenario
Fernando de Melo, Gabriel Dias Carvalho, Pedro S. Correia +3
Quantum mechanics started out as a theory to describe the smallest scales of energy in Nature. After a hundred years of development it is now routinely employed to describe, among…
