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…
Near-Unity Charge Readout in a Nonlinear Resonator without Matching
Harald Havir, Andrea Cicovic, Pierre Glidic +4
Dissipative sensors typically use linear resonators with impedance matching to achieve maximal signal and fast operation. The impedance matching, however, sets an upper limit to th…
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…
A coherence sweet spot with enhanced dipolar coupling
Jann H. Ungerer, Alessia Pally, Stefano Bosco +9
Qubits require a compromise between operation speed and coherence. Here, we demonstrate a compromise-free singlet-triplet (ST) qubit, where the qubit couples maximally to the drivi…
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…
