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…

DQC1 as an Open Quantum System

Jake Xuereb, Steve Campbell, John Goold +1

The DQC1 complexity class, or power of one qubit model, is examined as an open quantum system. We study the dynamics of a register of qubits carrying out a DQC1 algorithm and show…

Evidence of Kardar-Parisi-Zhang scaling on a digital quantum simulator

Nathan Keenan, Niall Robertson, Tara Murphy +2

Understanding how hydrodynamic behaviour emerges from the unitary evolution of the many-particle Schrödinger equation is a central goal of non-equilibrium statistical mechanics. In…

Entanglement enhanced metrology with quantum many-body scars

Shane Dooley, Silvia Pappalardi, John Goold

Although entanglement is a key resource for quantum-enhanced metrology, not all entanglement is useful. For example in the process of many-body thermalisation, bipartite entangleme…

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…
