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…
Observation of three-photon bound states in a quantum nonlinear medium
Qi-Yu Liang, Aditya V. Venkatramani, Sergio H. Cantu +7
Bound states of massive particles, such as nuclei, atoms or molecules, constitute the bulk of the visible world around us. In contrast, photons typically only interact weakly. We r…
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…
