All-optical control of the silicon-vacancy spin in diamond at millikelvin temperatures
Jonas Nils Becker, Benjamin Pingault, David Groß +7
The silicon-vacancy center in diamond offers attractive opportunities in quantum photonics due to its favorable optical properties and optically addressable electronic spin. Here,…
Optical coherence of Er:LiYF crystal below 1 Kelvin
Nadezhda Kukharchyk, Dmitriy Sholokhov, Stella L. Korableva +2
We explore spin dynamics of isotopically purified Er:LiYF crystal below 1 Kelvin and at weak magnetic fields 0.3 T. Crystals grown in our lab demonstrate recor…
Electromagnetic properties of terbium gallium garnet at millikelvin temperatures and single photon energy
Nikita Kostylev, Maxim Goryachev, Pavel Bushev +1
Electromagnetic properties of single crystal terbium gallium garnet (TGG) are characterised from room down to millikelvin temperatures using the whispering gallery mode method. Mic…
Low-Temperature Microwave Properties of Biaxial YAlO3
N. C. Carvalho, M. Goryachev, J. Krupka +2
Low-loss crystals with defects due to paramagnetic or rare earth impurity ions is a major area of investigation for quantum hybrid systems at both optical and microwave frequencies…
