Description
Point defects are localized irregularities in crystals that break the lattice symmetry of the hosting material. They can potentially be used in quantum technology as a room temperature qubit. Nitrogen-vacancy center (NV center) is the most studied point defect, where in the hosting diamond crystal two adjacent carbon atoms are switched to a nitrogen atom and a vacancy (empty spot).
The research of NV center is an immense success, resulting in demonstration of its capabilities across sensing, communication and computing. In sensing, NV center based technology reached commercialization.
While NV center is a major success due to its favorable properties, finding a similarly favorable point defect among the tens of thousands of other point defects is very difficult: The mixed theoretical and experimental approach used for NV center cannot be replicated en masse.
In the Qutility project, we develop software to provide a much more streamlined workflow for new point defect based qubit discovery.
We develop Quandidate, an ab-initio, wavefunction theory based software package, which has the unique capability to predict the relevant properties of a point defect or molecule, which decide if it can be engineered into a useful qubit. The prediction is based on predicting relaxation rates of the excited states of point defects and molecules.
Our Simphony open-source software models the spin dynamics of any point defect, providing a virtual laboratory for such physical systems.
The QUASAR package is a quantum compiler, capable of compiling logical circuits to the native gateset of central spin systems.
We also develop Qutility Frontier, a scalable and hardware-agnostic quantum benchmarking protocol.
