With quantum physics being more and more a part of our daily lives, there is a high demand of bringing its concepts and fundamentals to the public. We are using a open source and 3D-printed experiment platform [1] to enable hands-on quantum experiment kits like BB84 [2], quantum eraser [2], interferometers [3] and quantum sensing [4].
Here, we present our current progress towards a new kit controlling nitrogen-14 spin ensembles in bulk diamond, mediated by the NV electron spin. By tuning the system into the excited state level anticrossing (ESLAC) regime, the nuclear spin can be optically polarized. Coherent nuclear spin control is enabled by RF signals. This experiment builds on our existing kit of coherent control of the NVs electron spin and demonstrates both the electron-nuclear spin interaction and the distinct spin dynamics of nuclear spins compared to electron spins.
