Memory-Assisted Quantum Key Distribution with a Single Nitrogen-Vacancy Center

Single-Qubit Operations with the Nitrogen-Vacancy Center in Diamond

A concept combining optics and microwave pulses with the negative charge-state of the nitrogenvacancy (NV– ) center in diamond is demonstrated through experiments that are equivalent to single-qubit gates, and decoherence for this qubit is examined. The spin levels of the ground state provide the two-level system. Optical excitation provides polarization of these states. The polarized state is ...

Scanning localized magnetic fields in a microfluidic device with a single nitrogen vacancy center.

Nitrogen vacancy (NV) color centers in diamond enable local magnetic field sensing with high sensitivity by optical detection of electron spin resonance (ESR). The integration of this capability with microfluidic technology has a broad range of applications in chemical and biological sensing. We demonstrate a method to perform localized magnetometry in a microfluidic device with a 48 nm spatial...
