Time resolved correlation of microwave photons produced by inelastic tunneling of Copper pairs

We explore the characteristics of a source of anti-bunched microwave photons. This source has been developed by Max Hofheinz’s and its stationary properties have been characterized. In order to fully characterize this source when operated with pulse excitation, we modify the experimental setup and develop new numerical tools to extract the time resoled first and second order photon correlation function. We demonstrate that the emission is well synchronized with the pulse. Moreover we show the influence of several parameters and restrain their parameter space where a single photon emission can occur. Finally we demonstrate the existence of anti-bunched microwave photon emission from our sample and propose a way to optimize these parameters.
