Integrated Laser for Trapped Ion Quantum Computers

The overall goal of the STTR effort is to develop a compact, robust laser for cooling, re-pumping, state preparation and state detection of ytterbium-based trapped ion quantum computers.  Researchers and developers of trapped ion systems are often limited by the stability and reliability of the UV-Visable laser sources and components needed in their systems.  In this Phase I proposal, AdvR will establish the feasibility of making a narrowband laser source, which includes spectral modulation, that is reliable, stable, and scalable for use in multi qubit trapped ion systems.  In this work, AdvR will target Yb systems at 369nm; however, the technology is transferable to systems at other wavelengths.  AdvR's STTR partner institution, the University of California Los Angeles, has a proven research record with several trapped ion species of interest, thus ensuring the laser source will have the functionality required to significantly simplify the Yb laser system and accelerate research in the trapped ion quantum computing field.
