Information Thermodynamics in a Quantum Dot Szilard Engine - Experimentally Investigating Fluctuation Theorems and Thermodynamic Uncertainty Relations
David Barker, Sebastian Lehmann, Kimberly A. Dick +3
In Szilard's engine, measurement and feedback allows to extract work from an equilibrium environment, a process otherwise forbidden by the laws of thermodynamics. Recent theoretica…
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…
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,…
Maxwell's demon across the quantum-to-classical transition
Björn Annby-Andersson, Debankur Bhattacharyya, Pharnam Bakhshinezhad +5
In scenarios coined Maxwell's demon, information on microscopic degrees of freedom is used to seemingly violate the second law of thermodynamics. This has been studied in the class…
