The technology that underpins atomic clocks is critical to many of the proposed commercial quantum solutions. All rely on probing atomic/ionic transitions that can be extremely sensitive to environmental effects and present challenges in providing low cost, robust fieldable solutions. Approaches must satisfy not only highest performance applications, but also have a broad enough market appeal to ensure ready supply. In this tutorial, we will discuss the challenges that atomic clock and future quantum technology face, with respect to not only the technical approach, but also the supply chain issues that must be addressed. Richard Overstreet is Chief Scientist at the Microchip Frequency and Time Systems location in Beverly, MA and focuses on development of volume manufacturable atomic clocks at all levels of SWaP-C.
