Abstract

Current research in the field of quantum computing seeks to find suitable materials and systems that meet the criteria to be used as quantum bits, or qubits. Carbon has many properties that make it an ideal host lattice for such systems, and already some defect centers, most notably the nitrogen-vacancy (NV) center, have been identified as good candidates for quantum computing applications. Raman spectroscopy, known to provide a good measure of the purity of synthesized diamond films, was used to characterize single crystal diamond samples containing different types of defects and impurities. Spectra collected at 785 nm excitation displayed additional peaks that are thought to be a result of resonant enhancement of single defect states in the diamond sample. Further characterization is needed to identify the specific origin of each peak, but these results indicate that Raman spectroscopy holds promise as a method to identify and measure individual defect states in diamond.
