摘要:Current spin-magnetic resonance spectrometers are based on the
principle of ensemble detection and the test object is an ensemble
sample containing billions of identical spins. However, at room
temperature NMR at nano-scale is still a huge challenge. To achieve
the scientific goal, we choose single spins in solids based on NV
defect center in diamond - (NV) as the sensitivity magnetic probe. The
single NV spin can be easily visualized, polarized and detected with a
confocal microscope. Ultra-long spin coherence time for such qubits,
even at room temperature, enables it is ultra-sensitivity to external
magnetic noise with characteristic frequency. Instead of traditional
electrical defect, weak magnetic signals generated by the nano-scale
spin system is mapped to coherent state phase, so as to realize high
sensitivity signal detection.
