Abstract

Some aspects of existing and breakthrough technologies are approaching current physical limitations. For example, integrated circuits-based technologies are pushing the limits of Moore's Law [1]. Light, integrated photonics, and quantum materials afford new spaces for opportunities and innovation beyond these limits.

 

Nitrogen-Vacancy (NV) centers in diamonds, where each center is a nitrogen atom coupled with an atom vacancy combined defect, offer an example of one such innovation and breakthrough spaces. According to Childress et al. [2], NV centers "feature tightly localized electronic states that resemble those of single atoms frozen inside a solid lattice". These 'atom-like' [2] markers are sensitive to external atom-scale fields and they can be addressed (prepared) and probed (output) by readily available laser light source and detection means.   Significantly, these operate quantum mechanically so afford coherence and entanglement possibilities [2].

 

NV centers therefore have potential in applications including quantum computing, nano resolution in magnetic resonance imaging (optical detection magnetic resonance ODMR [3]), and precision metrology [2,3]. These systems may have the potential to be incorporated onto a photonic chip.

 

We are constructing a free-space NV center ODMR precision magnetometer, the first of its kind at BSU. We are building this light-based quantum sensor and performing experiments entirety as detailed by Zhang et al. [3]. Funding for our equipment is through a BSU CARs FLRG award (Deveney) and the research is performed through a BSU PHYS396 course.
