Operando Temperature Sensing at the Actual Electrocatalytic Interface by Nanodiamond Quantum Sensors

Advanced Functional Materials, EarlyView.
By integrating a wide‐field microscope with a custom‐designed electrolyzer, nanoscale temperature changes can be recorded in situ during the electrolysis process without interfering with ongoing electrochemical reactions. This method establishes a correlation between the interface temperature and specific electrochemical reactions, making the measured ...

Entangled mechanical cat states via conditional single photon optomechanics

New Journal of Physics, 2013
We study single photon optomechanics conditioned on photon counting events. By selecting only detection events that occur long after a photon pulse arrives at the cavity, the optomechanical interaction time can be increased, allowing a large momentum ...

Sub-Natural Linewidth Single Photons from a Quantum Dot

, 2011
The observation of quantum dot resonance fluorescence enabled a new solid-state approach to generating single photons with a bandwidth almost as narrow as the natural linewidth of a quantum dot transition.

Impact of Surface Functionalization on NV Quantum Properties: Implications for Biosensing with Fluorescent Nanodiamonds

Advanced Functional Materials, EarlyView.
Fluorescent nanodiamonds (fNDs) have emerged as an invaluable quantum sensing platform for biological and biochemical systems. This paper investigates the influence of common surface functionalization strategies for bioconjugation on the quantum properties of nitrogen vacancy (NV) centers in nanodiamonds.

Oxide-apertured microcavity single-photon emitting diode

, 2007
We have developed a microcavity single-photon source based on a single quantum dot within a planar cavity in which wet-oxidation of a high-aluminium content layer provides lateral confinement of both the photonic mode and the injection current.

Coexisting Rashba/Dresselhaus Spin Splitting in Solution‐Processed Bournonite Films Using Circular Photogalvanic Effect

Advanced Functional Materials, EarlyView.
Circular photogalvanic effect measurements and first‐principles calculations reveal spin‐splitting states in solution‐processed bournonite films (CuPbSbS3) due to structural and bulk inversion asymmetry. The results provide experimental confirmation of coexisting Rashba and Dresselhaus spin‐splitting states in this non‐centrosymmetric chalcogenide ...

Deterministic photon source of genuine three-qubit entanglement

Nature Communications
Deterministic photon sources allow long-term advancements in quantum optics. A single quantum emitter embedded in a photonic resonator or waveguide may be triggered to emit one photon at a time into a desired optical mode.
