The Brief
- The study measures spin-lattice relaxation times of electron spins in Er3+:CaWO4.
- The spins are coupled to a low mode-volume superconducting resonator.
- The measurements were made at millikelvin temperatures.
Why it matters
The work examines how phonons limit spin relaxation when spins are coupled to superconducting resonators at millikelvin temperatures, which bears on designing spin-based quantum devices that use such hardware.
