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,…
Time-resolved Stochastic Dynamics of Quantum Thermal Machines
Abhaya S. Hegde, Patrick P. Potts, Gabriel T. Landi
Steady-state quantum thermal machines are typically characterized by a continuous flow of heat between different reservoirs. However, at the level of discrete stochastic realizatio…
Role of Quantum Coherence in Kinetic Uncertainty Relations
Kacper Prech, Patrick P. Potts, Gabriel T. Landi
The Kinetic Uncertainty Relation (KUR) bounds the signal-to-noise ratio of stochastic currents in terms of the number of transitions per unit time, known as the dynamical activity.…
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…
Optimal time estimation and the clock uncertainty relation for stochastic processes
Kacper Prech, Gabriel T. Landi, Florian Meier +4
Time estimation is a fundamental task that underpins precision measurement, global navigation systems, financial markets, and the organisation of everyday life. Many biological pro…
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…
