On-demand microwave generator of shaped single photons

ORAL

Abstract

We present results of a microwave single-photon generator where the emission rate of a superconducting qubit is controlled in real time and photon wavepackets are emitted with a shaped profile. Controlling the radiative properties of quantum emitters has important applications in quantum information science. Arbitrarily shaped photon wavepackets could have an important role in, e.g., quantum networks as well as connecting spatially-isolated sectors of future quantum processors. The modulation is achieved by controlling the position of the nodes of vacuum modes in a semi-infinite transmission line shunted by a dc-SQUID. Besides its practical application as a photon source, this work enables fundamental studies of artificial atoms interacting with a quantum vacuum, leading to controlled dissipative processes and their effect in quantum information applications.
