Fast Preparation and Detection of a Rydberg Qubit using Atomic Ensembles
Wenchao Xu, Aditya V. Venkatramani, Sergio H. Cantú +4
We demonstrate a new approach for fast preparation, manipulation, and collective readout of an atomic Rydberg-state qubit. By making use of Rydberg blockade inside a small atomic e…
Repulsive photons in a quantum nonlinear medium
Sergio H. Cantu, Aditya V. Venkatramani, Wenchao Xu +4
The ability to control strongly interacting light quanta (photons) is of central importance in quantum science and engineering. Recently it was shown that such strong interactions…
Effect of higher-order nonlinearities on amplification and squeezing in Josephson parametric amplifiers
Samuel Boutin, David M. Toyli, Aditya V. Venkatramani +3
Single-mode Josephson junction-based parametric amplifiers are often modeled as perfect amplifiers and squeezers. We show that, in practice, the gain, quantum efficiency, and outpu…
