Light-Matter Interaction in dispersive Superconducting Circuit QED
Harsh Arora, Jay Deshmukh, Ansh Das +2
It is well known that superconducting waveguides strongly attenuate the propagation of electromagnetic waves with frequencies beyond the superconducting gap. In circuit QED, the in…

On-demand single-microwave-photon source in a superconducting circuit with wideband frequency tunability
Samarth Hawaldar, Siddhi Satish Khaire, Per Delsing +1
In this article, we propose a new method of generating single microwave photons in superconducting circuits. We theoretically show that pure single microwave photons can be generat…
