  • quEDU in combination with the nitrogen vacancy center experiment board.
  • Overview
  • Key Features
  • Applications
  • Sample Experiments
The NV experiment board allows you to experience the properties of nitrogen vacancy centers in diamond, such as NV center fluorescence, electron spin manipulation, optically detected magnetic resonance, and basic qubit operations.

The device comes in a compact design suited for a lab table or lecture hall with the optics enclosed and the electronics in the base of the device. The NV centers in the diamond and all optics are encapsulated by acrylic glass to ensure laser safety.

At the heart of the NV is a green laser focused on the nitrogen-doped diamond through a microscope objective. The diamond begins to fluoresce in the red wavelength range. This light is collected by the objective and, after some filtering, is coupled into a fiber. The fiber is connected to the quEDU and the fluorescence can be analyzed.

The sample itself contains three diamonds and can be aligned by linear stages. It also is in close proximity to a microwave antenna and is surrounded by coils producing a homogeneous magnetic field. That field can be manipulated in all dimensions.

In addition, the quEDUs included pattern generator is precisely controlling pulse sequences for laser, microwave, and readout, enabling a multitude of spin-control experiments.

The dynamics of the NV center allow applications like spin initialization and state readout. Therefore, the center is suitable for quantum sensing applications like magnetic field sensing, spin relaxation time measurements and optically detected magnetic resonance (ODMR).

Due to their scalability, long coherence times and ability for interaction with photons, NV centers are of high interest for research in quantum information processing. Qubits can be defined as spin states of single electron or nuclear spins.

Possible applications of the quEDU-NV are:
