Researchers recently developed a technique to record the quantum mechanical behavior of one electron in a nanoscale defect in diamond. The team used ultra-fast pulses of laser light both to control the defect's entire quantum state and to observe how the state of one electron in the defect changes over time. "This experiment uses a 'trapped' electron contained within the negatively charged NV center," said team leader David Awschalom, which "results in a well isolated trapped electron whose spin state can be used as our qubit."Scientists Zap Diamond With Laser to Record Quantum Behavior
