Abstract: Quantum computation has been drawing more and more attentions, since the Shor's algorithm and Grover's algorithm are proposed in the middle 1990s. Among the systems being pursued for physically implementing a quantum computer, the diamond solid-state quantum computation, which use the electronic or nuclear spins of nitrogen-vacancy (NV) centers as qubits, is considered more favorable because it has a super long coherence time at room temperature and precise manipulations for the system are readily available. In addition, NV centers may be used for single spin detection by magnetic resonance. For NV centers with a distance of tens of nanometers among them, the inter-center force will be strong enough to establish a quantum computer. However, the conventional confocal microscopy can only be used to resolve centers that are more than two hundred nanometers away from each other. Super-resolution microscopy techniques, such as stimulated emission depletion (STED) and ground state depletion (GSD), may provide a way to resolve NV centers with a resolution beyond the diffraction limit. In recent year, super-resolution microscopy has been used in combination with advanced surface processing technology for accurate positioning of NV centers in diamond. In this paper, we briefly summarize the super-resolution microscopy techniques that have been used in diamond solid-state quantum computation, and reviewed the latest developments in the field.
