Coherence of an Electronic Two-Level System under Continuous Charge Sensing by a Quantum Dot Detector
Subhomoy Haldar, Morten Munk, Harald Havir +7
We investigate experimentally the quantum coherence of an electronic two-level system in a double quantum dot under continuous charge detection. The charge-state of the two-level s…
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…
Continuous microwave photon counting by semiconductor-superconductor hybrids
Subhomoy Haldar, David Barker, Harald Havir +4
The growing interest in quantum information has enabled the manipulation and readout of microwave photon states with high fidelities. The presently available microwave photon count…
