Programmable all-to-all entangling gates for cavity-coupled atoms
Angus Crookes, Ben Yuen, Angela Demetriadou
Fault tolerant quantum computers greatly benefit from having both high fidelity entangling gates and a non-local qubit connectivity. However, most entangling gates for neutral atom…
Extreme mid-infrared field enhancement and anapoles in high-index plasmonic metamaterials
Zoltan Sztranyovszky, Nicolas Spiesshofer, Caleb Todd +5
High-refractive-index materials underpin a wide range of optical technologies, including communications, imaging, lasers, and integrated photonic systems. Here, we demonstrate a se…
Collective multimode strong coupling in plasmonic nanocavities
Angus Crookes, Ben Yuen, Angela Demetriadou
Plasmonic nanocavities enable access to the quantum properties of matter, but are often simplified to single mode models despite their complex multimode structure. Here, we show th…
Multi-partite entanglement in extreme nanophotonic cavities
Angus Crookes, Ben Yuen, Stephen M. Hanham +1
Multi-partite entanglement is fundamental to emerging quantum technologies such as quantum networks, which ultimately require devices with strong light-matter interactions and long…
Taming plasmonic nanocavities for subradiant entanglement
Angus Crookes, Ben Yuen, Angela Demetriadou
Recent rapid advances in quantum nanoplasmonics offer the potential for accessing quantum phenomena at room temperature. Despite this, entangled states have not yet been realised,…
Exact Quantum Electrodynamics in Radiative Photonic Environments
Ben Yuen, Angela Demetriadou
We present a comprehensive second quantization scheme for radiative photonic devices. We canonically quantize the continuum of photonic eigenmodes by transforming them into a discr…
Subradiant entanglement in plasmonic nanocavities
Kalun Bedingfield, Benjamin Yuen, Angela Demetriadou
Plasmonic nanocavities are known for their extreme field enhancement and sub-wavelength light confinement in gaps of just a few nanometers. Pairing this with the ability to host qu…
Multi-faceted plasmonic nanocavities
Kalun Bedingfield, Eoin Elliott, Arsenios Gisdakis +3
Plasmonic nanocavities form very robust sub-nanometer gaps between nanometallic structures and confine light in deep subwavelength volumes to enable unprecedented control on light-…
On the Excitation and Radiative Decay Rates of Plasmonic Nanoantennas
Kalun Bedingfield, Angela Demetriadou
Plasmonic nanoantennas have the ability to confine and enhance incident electromagnetic fields into very sub-wavelength volumes, while at the same time efficiently radiating energy…

Emiliano Cortés, Lucas V. Besteiro, Alessandro Alabastri +4
The use of nanoplasmonics to control light and heat close to the thermodynamic limit enables exciting opportunities in the field of plasmonic catalysis. The decay of plasmonic exci…
Plasmonic nanocavity modes: From near-field to far-field radiation
Nuttawut Kongsuwan, Angela Demetriadou, Matthew Horton +3
In the past decade, advances in nanotechnology have led to the development of plasmonic nanocavities which facilitate light-matter strong coupling in ambient conditions. The most r…
Mapping nanoscale hotspots with single-molecule emitters assembled into plasmonic nanocavities using DNA origami
Rohit Chikkaraddy, V. A. Turek, Nuttawut Kongsuwan +8
Fabricating nanocavities in which optically-active single quantum emitters are precisely positioned, is crucial for building nanophotonic devices. Here we show that self-assembly b…
Suppressed Quenching and Strong Coupling of Purcell-Enhanced Single-Molecule Emission in Plasmonic Nanocavities
Nuttawut Kongsuwan, Angela Demetriadou, Rohit Chikkaraddy +5
An emitter in the vicinity of a metal nanostructure is quenched by its decay through non-radiative channels, leading to the belief in a zone of inactivity for emitters placed withi…
Anomalous spectral shift of near- and far-field plasmonic resonances in nano-gaps
Anna Lombardi, Angela Demetriadou, Lee Weller +5
The near-field and far-field spectral response of plasmonic systems are often assumed to be identical, due to the lack of methods that can directly compare and correlate both respo…
