Preparations and applications of single color centers in diamond

Advances in Physics: X, 2021
As a non-classical light source, single-photon source plays an essential role in the foundation of quantum physics and has been attracting a lot of attention of researchers over the world. Up to now, among different kinds of single-photon sources, single

Coherence of group-IV color centers [PDF]

Physical Review B, 2023
Group-IV color centers in diamond (SiV, GeV, SnV) have emerged as leading solid-state spin-photon interfaces for quantum information processing applications. However, these qubits require cryogenic temperatures to achieve high fidelity operation due to interactions with the thermal phonon bath.

Photolithographic Patterning of Organic Color‐Centers

Advanced Materials, 2020
AbstractOrganic color‐centers (OCCs) have emerged as promising single‐photon emitters for solid‐state quantum technologies, chemically specific sensing, and near‐infrared bioimaging. However, these quantum light sources are currently synthesized in bulk solution, lacking the spatial control required for on‐chip integration.

Improved Bounds for Centered Colorings [PDF]

Advances in Combinatorics, 2020
A vertex coloring $\phi$ of a graph $G$ is $p$-centered if for every connected subgraph $H$ of $G$ either $\phi$ uses more than $p$ colors on $H$ or there is a color that appears exactly once on $H$. Centered colorings form one of the families of parameters that allow to capture notions of sparsity of graphs: A class of graphs has bounded expansion if ...

Deterministic placement of ultra-bright near-infrared color centers in arrays of silicon carbide micropillars

Beilstein Journal of Nanotechnology, 2019
We report the enhancement of the optical emission between 850 and 1400 nm of an ensemble of silicon mono-vacancies (VSi), silicon and carbon divacancies (VCVSi), and nitrogen vacancies (NCVSi) in an n-type 4H-SiC array of micropillars.
