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,…
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…
Universally Robust Quantum Control
Pablo M. Poggi, Gabriele De Chiara, Steve Campbell +1
We study the robustness of the evolution of a quantum system against small uncontrolled variations in parameters in the Hamiltonian. We show that the fidelity susceptibility, which…
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…
Entropy of the quantum work distribution
Anthony Kiely, Eoin O'Connor, Thomás Fogarty +2
The statistics of work done on a quantum system can be quantified by the two-point measurement scheme. We show how the Shannon entropy of the work distribution admits a general upp…
Minimal action control method in quantum critical models
Ainur Kazhybekova, Steve Campbell, Anthony Kiely
We present a general protocol to control closed quantum systems that is based on minimising the adiabatic action. Using tools based on the geometry of quantum evolutions through th…
Non-Gaussian work statistics at finite-time driving
Krissia Zawadzki, Anthony Kiely, Gabriel T. Landi +1
We study properties of the work distribution of a many-body system driven through a quantum phase transition in finite time. We focus on the non-Gaussianity of the distribution, wh…
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…
Classical dissipative cost of quantum control
Anthony Kiely, Steve Campbell, Gabriel T. Landi
Protocols for non-adiabatic quantum control often require the use of classical time varying fields. Assessing the thermodynamic cost of such protocols, however, is far from trivial…
Optimal Control in Disordered Quantum Systems
Luuk Coopmans, Steve Campbell, Gabriele De Chiara +1
We investigate several control strategies for the transport of an excitation along a spin chain. We demonstrate that fast, high fidelity transport can be achieved using protocols d…
Counterdiabatic control in the impulse regime
Eoin Carolan, Anthony Kiely, Steve Campbell
Coherent control of complex many-body systems is critical to the development of useful quantum devices. Fast perfect state transfer can be exactly achieved through additional count…
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…
Fast and robust magnon transport in a spin chain
Anthony Kiely, Steve Campbell
A protocol for fast and robust magnon transport in a one-dimensional spin chain is devised. Employing an approximate mapping between the chain and a single harmonically trapped par…
Quantum-optical implementation of non-Hermitian potentials for asymmetric scattering
Andreas Ruschhaupt, Anthony Kiely, Miguel Ángel Simón +1
Non-Hermitian, one-dimensional potentials which are also non-local, allow for scattering asymmetries, namely, asymmetric transmission or reflection responses to the incidence of a…
Quantum Control via Enhanced Shortcuts to Adiabaticity
Chris Whitty, Anthony Kiely, Andreas Ruschhaupt
Fast and robust quantum control protocols are often based on an idealised approximate description of the relevant quantum system. While this may provide a performance which is clos…
Energetic cost of quantum control protocols
Obinna Abah, Ricardo Puebla, Anthony Kiely +3
We quantitatively assess the energetic cost of several well-known control protocols that achieve a finite time adiabatic dynamics, namely counterdiabatic and local counterdiabatic…
Shortcuts to adiabaticity: concepts, methods, and applications
D. Guéry-Odelin, A. Ruschhaupt, A. Kiely +3
Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes of the controlling parameters of a system. The shortcuts are designed by a set of an…
-matrix pole symmetries for non-Hermitian scattering Hamiltonians
M. A. Simón, A. Buendía, A. Kiely +2
The complex eigenvalues of some non-Hermitian Hamiltonians, e.g. parity-time symmetric Hamiltonians, come in complex-conjugate pairs. We show that for non-Hermitian scattering Hami…
Selective population of a large-angular-momentum state in an optical lattice
A. Kiely, J. G. Muga, A. Ruschhaupt
We propose a method to selectively populate a large angular momentum state of ultracold atoms (each with an orbital angular momentum ) in the Mott regime of a tw…
Noise Resistant Quantum Control Using Dynamical Invariants
Amikam Levy, A. Kiely, J. G. Muga +2
A systematic approach to design robust control protocols against the influence of different types of noise is introduced. We present control schemes which protect the decay of the…
Spatial non-adiabatic passage using geometric phases
Albert Benseny, Anthony Kiely, Yongping Zhang +2
Quantum technologies based on adiabatic techniques can be highly effective, but often at the cost of being very slow. Here we introduce a set of experimentally realistic, non-adiab…

Anthony Kiely, Albert Benseny, Thomas Busch +1
We propose a method to create higher orbital states of ultracold atoms in the Mott regime of an optical lattice. This is done by periodically modulating the position of the trap mi…
