Thermodynamics of a continuously monitored double quantum dot heat engine in the repeated interactions framework
Laetitia P. Bettmann, Michael J. Kewming, John Goold
Understanding the thermodynamic role of measurement in quantum mechanical systems is a burgeoning field of study. In this article, we study a double quantum dot (DQD) connected to…
Quantum Kernel Evaluation via Hong-Ou-Mandel Interference
Cassandra Bowie, Sally Shrapnel, Michael Kewming
One of the fastest growing areas of interest in quantum computing is its use within machine learning methods, in particular through the application of quantum kernels. Despite this…
Effect of Measurement Backaction on Quantum Clock Precision Studied with a Superconducting Circuit
Xin He, Prasanna Pakkiam, Adil A. Gangat +3
We theoretically and experimentally study the precision of a quantum clock near zero temperature, explicitly accounting for the effect of continuous measurement. The clock is creat…
Quantum thermodynamics with fast driving and strong coupling via the mesoscopic leads approach
Artur M. Lacerda, Archak Purkayastha, Michael Kewming +2
Understanding the thermodynamics of driven quantum systems strongly coupled to thermal baths is a central focus of quantum thermodynamics and mesoscopic physics. A variety of diffe…
Comment on "Thermodynamic Principle for Quantum Metrology"
Shane Dooley, Michael J. Kewming, Mark T. Mitchison +1
In Phys. Rev. Lett. 128, 200501 (2022) the authors consider the thermodynamic cost of quantum metrology. One of the main results is $\mathcal{S} \geq \log(2) \| h_λ\|^{-2} F_Q [ψ_λ…
Diverging current fluctuations in critical Kerr resonators
Michael J. Kewming, Mark T. Mitchison, Gabriel T. Landi
The parametrically pumped Kerr model describes a driven-dissipative nonlinear cavity, whose nonequilibrium phase diagram features both continuous and discontinuous quantum phase tr…
Measurement based estimator scheme for continuous quantum error correction
Sangkha Borah, Bijita Sarma, Michael Kewming +3
Canonical discrete quantum error correction (DQEC) schemes use projective von Neumann measurements on stabilizers to discretize the error syndromes into a finite set, and fast unit…
