Measuring Interaction-Induced Energy Shifts of Rydberg Atoms in Hot Vapor
Tomasz Prokop, Bartosz Kasza, Wojciech Wasilewski +1
We demonstrate a method to measure energy shifts of the top level in a four-level ladder setup induced by atom interactions in thermal vapors. It utilizes the observation of two tr…
Multiplexed storage and interaction of Rydberg spinwaves via the gradient echo memory protocol
Bartosz Niewelt, Stanisław Kurzyna, Bartosz Kasza +2
Collective Rydberg excitations offer strong and controllable interactions for quantum information processing, sensing, and nonlinear quantum optics, but their integration with temp…
Electric-field metrology of a terahertz frequency comb using Rydberg atoms
Wiktor Krokosz, Jan Nowosielski, Bartosz Kasza +4
Terahertz radiation finds an increasing number of applications, yet efficient generation and detection remain a challenge and an active area of research. In particular, the precise…
Atomic-optical interferometry in fractured loops: a general solution for Rydberg radio frequency receivers
Bartosz Kasza, Sebastian Borówka, Wojciech Wasilewski +1
The development of novel radio frequency atomic receivers brings attention to the theoretical description of atom-light interactions in sophisticated, multilevel schemes. Of specia…
