Qubit-parity interference despite unknown interaction phases
Kratveer Singh, Kimin Park, Vojtěch Švarc +5
Quantum interference between interacting systems is fundamental to basic science and quantum technology, but it typically requires precise control of the interaction phases of lase…

Sub-Planck structure quantification in non-Gaussian probability densities
Darren W. Moore, Vojtěch Švarc, Kratveer Singh +5
Sub-Planck structures in non-Gaussian probability densities of phase space variables are pervasive in bosonic quantum systems. They are almost universally present if the bosonic sy…

A many-particle bosonic quantum Maxwell demon
Josef Hloušek, Tobias Denzler, Vojtěch Švarc +3
Energy extraction from a measured quantum system is a cornerstone of information thermodynamics as illustrated by Maxwell's demon. The nonequilibrium physics of many-particle syste…
