Wigner-function formalism for the detection of single microwave pulses in a resonator-coupled double quantum dot
Drilon Zenelaj, Peter Samuelsson, Patrick P. Potts
Semiconductor double quantum dots (DQD) coupled to superconducting microwave resonators offer a promising platform for the detection of single microwave photons. In previous works,…

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…

Microwave power harvesting using resonator-coupled double quantum dot photodiode
Subhomoy Haldar, Drilon Zenelaj, Patrick P. Potts +5
We demonstrate a microwave power-to-electrical energy conversion in a resonator-coupled double quantum dot. The system, operated as a photodiode, converts individual microwave phot…
