Generating uniform quantum state ensembles with continuous measurement
Theodore McKeever, Ahsan Nazir, Harry J. D. Miller
We investigate the generation of uniform quantum state ensembles via continuous measurement. Using the Bloch representation, we derive the associated Langevin and Fokker-Pl…
An Introduction to the Foundations and Interpretations of Quantum Mechanics
Theodore McKeever, Ahsan Nazir
This article surveys a selection of key conceptual and interpretational developments in quantum mechanics, tracing the theory from its foundational postulates to contemporary discu…
The role of polarization field terms in a model for a cavity quantum material
Arwen Lloyd, Adam Stokes, Alessandro Principi +1
Constructing models for cavity quantum materials requires a careful treatment of the light-matter coupling. In general, one must specify matrix elements constructed from the materi…
Long-range quantum emitter interactions mediated by a non-local metasurface: Application to qubit-qubit entanglement
Hannah Riley, Emmanuel Lassalle, Diego Romero Abujetas +3
Scalable quantum technologies demand long-range interactions between many distant quantum emitters (QEs). We introduce non-local metasurfaces supporting bound-states-in-the-continu…
Finite steps optimise dissipation in stochastically controlled quantum systems
Theodore McKeever, Harry J. D. Miller, Ahsan Nazir
Motivated by the need for precise, energy-efficient, and experimentally realistic quantum control protocols, we investigate the thermodynamic cost of performing quantum step-equili…
Operator Space Transport and the Emergence of Boundary Time Crystals
Dominik Nemeth, Ahsan Nazir, Robert-Jan Slager +1
Boundary time crystals (BTCs) are prominent examples of continuous time crystals in collective spin systems governed by Lindbladian evolution. To date, their analysis has mostly re…
