Nanoscale graphitization and defect evolution in silicon-vacancy center-containing nanodiamonds under high-pressure high-temperature annealing
M. De Feudis, B. Yavkin, L. Henry +6
Group-IV color centers, such as the silicon-vacancy (SiV) defect, are highly promising for solid-state quantum technologies. However, nanodiamonds typically exhibit significant lat…
Optical Stability and Photophysics of NV Centers in Diamond up to 120 GPa
Kin On Ho, Cassandra Dailledouze, Vytautas Žalandauskas +9
The nitrogen vacancy (NV) center has emerged as a powerful quantum sensor in high-pressure research, with the observation of optically detected magnetic resonance at megabar pressu…
Widefield NV Magnetic Field Reconstruction for Probing the Meissner Effect and Critical Current Density under Pressure
Kin On Ho, Cassandra Dailledouze, Martin Schmidt +3
The spatial distribution of a magnetic field can be determined with micrometer resolution using widefield nitrogen vacancy (NV) center magnetic imaging. Nevertheless, reconstructin…
Enhancement of quantum coherence in solid-state qubits via interface engineering
Wing Ki Lo, Yaowen Zhang, Ho Yin Chow +8
Shallow nitrogen-vacancy (NV) centers in diamond are promising quantum sensors but suffer from noise-induced short coherence times due to bulk and surface impurities. We present in…
Imaging the Meissner Effect and Flux Trapping of Superconductors under High Pressure using N-V Centers
Cassandra Dailledouze, Antoine Hilberer, Martin Schmidt +7
Pressure is a key parameter for tuning or revealing superconductivity in materials and compounds. Many measurements of superconducting phase transition temperatures have been condu…
