Quantum Resonator as a Directional Quantum Emitter

Advanced Quantum Technologies
ABSTRACT Single‐photon sources are essential for testing fundamental physics and for the development of quantum technologies. In this work, a single‐photon source is investigated, based on a two‐photon Jaynes–Cummings system, where the resonator works as the quantum emitter rather than the two‐level system. This role reversal provides

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Suppression of local decay rate through energy quantum confinement effect in non-Markovian waveguide QED

PhotoniX
Waveguide quantum electrodynamics (QED) system manifests an ideal platform for studying many-body physics. When multiple emitters are coupled to a common waveguide, subradiant states may arise because of the waveguide-mediated interaction, leading to a ...

Design of photonic microcavities in hexagonal boron nitride

Beilstein Journal of Nanotechnology, 2018
We propose and design photonic crystal cavities (PCCs) in hexagonal boron nitride (hBN) for diverse photonic and quantum applications. Two dimensional (2D) hBN flakes contain quantum emitters which are ultra-bright and photostable at room temperature. To

On-Chip Quantum Photonics Using Integrated Quantum Dot Emitters [PDF]

2018 20th International Conference on Transparent Optical Networks (ICTON), 2018
On-chip quantum photonics relies on the integration of efficient single-photon sources with advanced quantum- optical circuits. In this presentation, I will review progress at the University of Sheffield on a chip-compatible III-V semiconductor platform in which InGaAs quantum-dot (QD) single-photon emitters are integrated into GaAs photonic circuits ...

Two Coexisting Pathways to Volatility in Valence‐Change Memory Devices

Advanced Functional Materials, EarlyView.
Volatile VCM‐type memristive devices exhibit current relaxation after resistive switching, but their microscopic origin remains debated. Using pulsed measurements and a new Tunnel‐DLTS approach on Pt/SrTiO3/Nb:SrTiO3 devices, we show that post‐SET volatility is predominantly ionic, while electronic contributions—arising from quasi‐Fermi‐level ...
