A hands-on activity to introduce the structure of NV-center quantum bits in diamond

Abstract

For the start of a secondary school level lesson series on quantum computing, we designed a hands-on modeling activity where students construct a model diamond lattice with a nitrogen vacancy (NV) defect. NV centers find application as qubits and sensitive magnetometers. This activity aims to help students visualize the structure of such NV centers within the diamond lattice, making the subject matter more tangible. The activity has proven to be challenging but feasible. It features both collaborative and competitive elements thereby surely creating an energizing buzz in the classroom.
