Metrological approach to the emergence of classical objectivity
Anthony Kiely, Diana A. Chisholm, Akram Touil +3
We present a precise characterization of the onset of classicality that combines the formalism of quantum Darwinism with the tools from quantum metrology. We show that the quantum…
Ergotopy transport in a one dimensional spin chain
Dara Murphy, Anthony Kiely, Irene D'Amico +1
We examine the transport of useful energy, i.e. extractable work as quantified by the ergotropy, along a spin chain with tuneable exchange couplings between the sites. We focus on,…
Improved anharmonic trap expansion through enhanced shortcuts to adiabaticity
C. Whitty, A. Kiely, A. Ruschhaupt
Shortcuts to adiabaticity (STA) have been successfully applied both theoretically and experimentally to a wide variety of quantum control tasks. In previous work the authors have d…
Robustness of Enhanced Shortcuts to Adiabaticity in Lattice Transport
Chris Whitty, Anthony Kiely, Andreas Ruschhaupt
Shortcuts to adiabaticity (STA) are a collection of quantum control techniques that achieve high fidelity outside of the adiabatic regime. Recently an extension to shortcuts to adi…
Operator growth and spread complexity in open quantum systems
Eoin Carolan, Anthony Kiely, Steve Campbell +1
Commonly, the notion of "quantum chaos'' refers to the fast scrambling of information throughout complex quantum systems undergoing unitary evolution. Motivated by the Krylov compl…
First Passage Times for Continuous Quantum Measurement Currents
Michael J. Kewming, Anthony Kiely, Steve Campbell +1
The First Passage Time (FPT) is the time taken for a stochastic process to reach a desired threshold. In this letter we address the FPT of the stochastic measurement current in the…
