Abstract: Single-photon emitters play an important role in many leading quantum technologies. There is still no 'ideal' on-demand single-photon emitter, but a plethora of promising material systems have been developed, and several have transitioned from proof-of-concept to engineering efforts with steadily improving performance. Point defects in semiconductors and insulators form an exciting system for the realization of single-photon emitters and quantum technologies, as they can provide the isolation necessary to maintain the coherence of quantum states while being easily manipulated through optics and electricity. Use can be made of first-principles calculations to identify, characterize, and develop said defects for quantum applications. Here I review the firstprinciples methodologies for calculating the relevant structural, electronic, vibrational, optical, and magnetic properties of defects for quantum technologies. Examples of the most recent endeavors in this area will be given and areas in which further development is desirable will be pointed out
