Abstract:
The Quantum Technologies Center at Rafael is dedicated to quantum research and development, focusing on two key fields: hot alkali vapors, and cold atom interferometry.
In the hot vapor lab, we work with alkali vapor cells containing odd isotopes of noble gases. These gases possess robust nuclear spins shielded by closed electron shells. However, these spins are optically inaccessible, which poses a significant experimental challenge. We address it by utilizing alkali atoms as intermediaries to access and manipulate noble gas spins. This technique allows us to harness the exceptionally long coherence and lifetime of the nuclear spins for various applications, including sensing and quantum information processing.
In the atom interferometry lab, we employ light-pulse atom interferometry to manipulate the momentum states of cold atoms. By utilizing coherent optical transitions, we create matter-wave optics akin to traditional optical components. This allows us to construct precision interferometers using atomic wave functions, enabling high-precision inertial measurement, such as acceleration, rotation, and gravity.
Here, I will present the fundamental principles of our research and discuss recent and ongoing works, ranging from purely academic pursuits to highly applicative projects.
