Quick Spin Flips Quantum computation holds the tantalizing promise of vastly improving efficiency traditional computers. Among many solid-state candidates for storing and manipulating quantum information, nitrogen vacancy centers in diamond are especially attractive because they can be used at room temperature stay operational milliseconds a time. To use this coherence time efficiently, it is important to achieve fast manipulation spins system. Fuchs et al. (p. 1520 , published online 19 November; see Perspective by Gerardot Öhberg ) pulses strong microwave magnetic field probe dynamics single center. In “strong-driving” nonlinear regime, extremely quick spin flips less than nanosecond duration were observed, offering possibility that up million operations could performed on during its
