What's New

Best Poster Award August 2019
The atom chip group realizes for the first time ever a full-loop Stern-Gerlach interferometer. It is now 100 years since Stern and Gerlach went into their Frankfurt laboratory to conduct one of the most famous experiments in quantum mechanics. It is only now that the long-time dream of a closed loop interferometer based on splitting and recombining with magnetic gradients is realized. Stern and Gerlach could not prove that their spin superposition maintains coherence under momentum and spatial splitting. We have now proved it! The finding is reported in Physical Review Letters. We intend to use this capability to further investigate the foundations of quantum theory.

Best Poster Award May, 2019
Our MSc student, Yosef Bivas, won the best poster award, for his poster on our Yb optical atomic clock. Optical clocks are probably the most precise machines ever built by humans, and several dozens of them now operate around the world. The accuracy is so high, that if you would turn on such a clock at the big bang, it would have today an error of much less than a second.

Best Poster Award December, 2018
The atom chip group wins a European grant (together with a consortium) to build a Yb optical atomic clock. This will be the most accurate atomic clock in Israel, and stand at the cutting edge of world clocks.

Best Poster Award October, 2018
Quantum technology is becoming hot all around the world. The atom chip group delivers first prototypes to the Israeli Aerospace Industry and to the Israeli Accubeat company for atomic clocks.
