IQIM Postdoctoral and Graduate Student Seminar
Abstract: The world of precision atom-, molecular-, and quantum-based scientific experiments, instrumentation, and discoveries, such as atomic clocks and quantum gravitational wave sensors, have the potential to undergo a transformation to the chip-scale much like computers of the 1950s. This transformation will unleash a wealth of new applications such as quantum computing, quantum sensing, atomic clocks and frequency metrology. Today, the experimental infrastructure for these precision experiments is made up of over 80% sophisticated light lab-scale laser, optical, and control equipment, with many of the atomic transitions and wavelengths in the visible. At the forefront of moving these technologies to the chip-scale is a new age of visible light integrated photonics that can bring about the reduction in size, power, and cost of these systems and enable vast new portable applications. This talk will cover our latest results in the ultra-low loss silicon nitride integration platform and atomic and quantum components and subsystems including frequency stabilized lasers, spectroscopic interrogation, and integration of beamlines for atom cooling, trapping, state preparation, and interrogation. Work on PIC based cold atom rubidium magnetooptic traps (3D-PICMOT) and other ion and neutral atom photonics will be described. Integrating these systems to the chip- scale, through visible light photonics, will enable new, reliable, and portable applications including space-based experiments, portable and integrated atomic clocks, quantum and atomic timing and gravitational sensors, cold-molecule physics and discoveries, and global satellite navigation systems (GNSS).
Lunch will be provided, following the talk, on the lawn north of the Bridge Arcade
