In response to the Armys STTR Topic A09A-T008- entitled Ultraviolet and blue compact laser sources for scalable quantum computing, Kaai Inc, proposes the development of a external cavity fiber coupled high efficiency GaN laser diode as a revolutionary source toward practical quantum computing based on ion trapping. Kaai is well suited for this effort as its co-founder, Dr. Shuji Nakamura, performed the first demonstration of a high brightness gallium nitride (GaN)-based blue laser diode (LD) and light emitting diode (LED) in the 1990s, and has founded Kaai specifically for the continued revolutionary developments of high power GaN devices. In order to enhance the GaN diode lasers applicability to quantum computing, The Pennsylvania State University Electro-Optics Center (EOC), as a subcontractor and a leader in electro-optic applied research, will achieve wavelength tunability and linewidth narrowing through an external optical cavity and will efficiently couple the GaN laser into a single mode fiber for practical beam delivery. The EOC is a NAVY Mantech center and a hub for electro-optic technologies. In support of Kaais proposal, The University of Maryland Joint Quantum Institute (JQI) shall advise the team on the detailed technical requirements to address trapped atomic ions for scalable quantum computing.
