New Hybrid Approach for Readout of NV Centers
Researchers at the University of Munich and the Munich Center for Quantum Science and Technology (MCQST) have made significant strides in quantum sensing technology, as detailed in a recent study published in Applied Physics Letters. The team has developed a novel method for both optical and electrical readout of nitrogen-vacancy (NV) centers in diamond with the help of the C-WAVE VIS Tunable laser. The C-WAVE provided tunable wavelengths from 450 to 526 nm and 540 to 650 nm with a linewidth of 10 MHz.
They found out that while the optical readout works best between 525 and 550 nm, the highest electrical spin contrast is achieved by resonantly exciting the NV zero-phonon line at 575 nm. These insights represent a major step forward in the field of quantum sensing, promising to unlock new possibilities for scientific and technological advancements.
