Quantum-dot circuit quantum electrodynamics (QD-cQED) has enabled the probe and control of light-matter interaction at the elementary level, with the demonstration of nonclassical photon sources driven by inelastic electron tunneling. Due to the absence of the photon blockade mechanism, an general scheme for photon statistics engineering in QD-cQED is lacking. Based on current-driven joint interference effect, the authors propose here an all-electrical scheme to achieve arbitrary photon statistics with classical or quantum correlation by simply controlling bias voltage.

Cavity quantum electrodynamics allows one to study the interaction between light and matter at the most elementary level. The methods developed in this field have taught us how to probe and manipulate individual quantum systems like atoms and superconducting quantum bits with an exquisite accuracy. There is now a strong effort to extend further these methods to other quantum systems, and in particular hybrid quantum dot circuits. This could turn out to be instrumental for a noninvasive study of quantum dot circuits and a realization of scalable spin quantum bit architectures. It could also provide an interesting platform for quantum simulation of simple fermion–boson condensed matter systems. In this short review, we discuss the experimental state of the art for hybrid circuit quantum electrodynamics with quantum dots, and we present a simple theoretical modeling of experiments.
