Imaging of Gate-Controlled Suppression of Superconductivity via the Meissner Effect
P. J. Scheidegger, K. J. Knapp, U. Ognjanovic +5
It was recently discovered that supercurrents flowing through thin superconducting nanowires can be quenched by a gate voltage. This gate control of supercurrents, known as the GCS…
Modeling temperature-dependent population dynamics in the excited state of the nitrogen-vacancy center in diamond
Stefan Ernst, Patrick J. Scheidegger, Simon Diesch +1
The nitrogen-vacancy (NV) center in diamond is well known in quantum metrology and quantum information for its favorable spin and optical properties, which span a wide temperature…
Temperature dependence of photoluminescence intensity and spin contrast in nitrogen-vacancy centers
Stefan Ernst, Patrick J. Scheidegger, Simon Diesch +2
We report on measurements of the photoluminescence (PL) properties of single nitrogen-vacancy (NV) centers in diamond at temperatures between 4-300 K. We observe a strong reduction…
Scanning nitrogen-vacancy magnetometry down to 350mK
Patrick J. Scheidegger, Simon Diesch, Marius L. Palm +1
We report on the implementation of a scanning nitrogen-vacancy (NV) magnetometer in a dry dilution refrigerator. Using pulsed optically detected magnetic resonance combined with ef…
NV-Diamond Magnetic Microscopy using a Double Quantum 4-Ramsey Protocol
Connor A. Hart, Jennifer M. Schloss, Matthew J. Turner +3
We introduce a double quantum (DQ) 4-Ramsey measurement protocol that enables wide-field magnetic imaging using nitrogen vacancy (NV) centers in diamond, with enhanced homogeneity…
