Abstract:
For almost 70 years now, Atomic clocks are being considered the most accurate and stable frequency standards. Hence, they have been serving important applications such as synchronization of communication networks, time measurement in GNSS networks, financial transactions timing and radar signals coordination.
Until 30 years ago, the atomic media applied for clocks consisted of vapors and atomic beams. However, the development of atom laser cooling enabled the establishment of atomic fountain clocks based on cold atom medium and showing ~10-16 uncertainty, about 2 orders of magnitude better than the former record. Nevertheless, these clocks are rather big and sensitive to temperature drifts, and thereby do not support field applications. Thus, several efforts have been done over the world in the recent years, to miniaturize and rigidize this technology with a minimal reduction in performance. Here, we review such an effort done by the Israeli company Accubeat, in collaboration with the atom chip lab in BGU. Time permitting, I will also briefly review my work in ELTA on a SC quantum computer.
