An analysis and improvement of the spectral properties nitrogen-vacancy defects in diamond nanostructures paves way for efficient entanglement generation necessary many quantum information applications.

The interactions between hydrogen, dislocations and vacancies that lead to the hydrogen embrittlement of iron-based materials have remained largely unknown with major impediments for development infrastructure transport storage. Recent studies hydrogen-induced lattice defects formed in pure iron common austenitic stainless steels by positron annihilation lifetime spectroscopy provided a breakth...

Silicon-vacancy and tin-vacancy defects in diamond are of interest as alternative qubits to the NV center due their superior optical properties. While availability transitions these is one assets, high-fidelity coherent control has not been demonstrated. Here, we design novel schemes tailored defects. We evaluate performance arbitrary single-qubit rotations electron spin qubit both absence pres...
