- Abstract: Diamond based quantum technology is a fast emerging field with both
scientific and technological importance. With the growing knowledge and
experience concerning diamond based quantum systems, comes an increased demand
for performance. Quantum optimal control (QOC) provides a direct solution to a
number of existing challenges as well as a basis for proposed future
applications. Together with a swift review of QOC strategies, quantum sensing
and other relevant quantum technology applications of nitrogen-vacancy (NV)
centers in diamond, we give the necessary background to summarize recent
advancements in the field of QOC assisted quantum applications with NV centers
in diamond.
