High-efficiency microwave photodetection by cavity coupled double dots with single cavity-photon sensitivity

Subhomoy Haldar, Harald Havir, Waqar Khan +6

We present a superconducting cavity-coupled double quantum dot (DQD) photodiode that achieves a maximum photon-to-electron conversion efficiency of 25% in the microwave domain. Wit…
