Perfect photons feed new quantum processor

A quantum processor working with photons developed at the University of Twente becomes an ever stronger ‘toolbox’ for doing experiments. The latest version not only has more inputs and outputs, it can also be fed by a photon source that is able to produce identical photons. Physical experiments, sometimes counterintuitive ones, are now possible. Can a system, for example, show quantummechanic and thermodynamic behavior at the same time?
