Fair colorful k-center clustering [PDF]
Mathematical Programming, 2020 AbstractAn instance of colorfulk-center consists of points in a metric space that are colored red or blue, along with an integer k and a coverage requirement for each color. The goal is to find the smallest radius $$\rho $$ ρ such that there exist balls of radius $$\rho $$ ρ around k

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 ...

Tunable Cr4+ Molecular Color Centers [PDF]
Journal of the American Chemical Society, 2021 The inherent atomistic precision of synthetic chemistry enables bottom-up structural control over quantum bits, or qubits, for quantum technologies. Tuning paramagnetic molecular qubits that feature optical-spin initialization and readout is a crucial step toward designing bespoke qubits for applications in quantum sensing, networking, and computing ...

Hands-On Quantum Sensing with NV− Centers in Diamonds
C, 2023 The physical properties of diamond crystals, such as color or electrical conductivity, can be controlled via impurities. In particular, when doped with nitrogen, optically active nitrogen-vacancy centers (NV), can be induced. The center is an outstanding
