Researchers at MIT and elsewhere have developed a technique that enables them to identify and control a greater number of these microscopic defects.
Their method builds off a central defect inside a diamond, known as a nitrogen-vacancy (NV) center, which scientists can detect and excite using laser light and then control with microwave pulses.
Technology could enable devices that image the brain with unprecedented detail.
To control a spin, the microwave pulses must be very close to the resonance frequency of that spin.
Tiny drifts in the experimental setup, due to temperature or vibrations, can throw off the pulses.
The researchers were able to optimize their protocol for sending precise microwave pulses, which enabled them to effectively identify and control second -layer spins.
