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…
Arbitrary gauge quantisation of light-matter theories with time-dependent constraints
Adam Stokes, Ahsan Nazir
We provide a general framework for the quantisation of light-matter theories with time-dependent holonomic constraints. Unless time dependence is present from the outset at the Lag…
Dicke Superradiance in Extended 2D Quantum Arrays Coupled to Metasurface Bound States in the Continuum
Daniel Eyles, Emmanuel Lassalle, Adam Stokes +2
Dicke superradiance is a collective phenomenon where the emission from ensembles of quantum emitters is coherently enhanced beyond the sum of each emitter's independent emission. H…
Sampling methods to describe superradiance in large ensembles of quantum emitters
Daniel Eyles, Emmanuel Lassalle, Adam Stokes +2
Superradiance is a quantum phenomenon in which coherence between emitters results in enhanced and directional radiative emission. Many quantum optical phenomena can be characterize…
Cauchy-Schwarz bound on the accuracy of truncated models in non-relativistic quantum electrodynamics
Daniel Eyles, Adam Stokes, Ahsan Nazir
We show that the Cauchy-Schwarz inequality provides a simple yet general bound that limits the accuracy of light-matter theories which retain only finite numbers of material energy…
