Spin readout via spin-to-charge conversion in bulk diamond nitrogen-vacancy ensembles

Harishankar Jayakumar, Siddharth Dhomkar, Jacob Henshaw +1

We demonstrate optical readout of ensembles of nitrogen-vacancy(NV) center spins in a bulk diamond sample via spin-to-charge conversion. A high power 594 nm laser is utilized to se…
