Multi-mode Parametric Coupling & the Field-Programmable Josephson Amplifier
Abstract: Josephson junction-based microwave parametric amplifiers are ubiquitous in quantum computing research based on superconducting circuits. However, they still leave a lot to be desired when it comes to scaling up to the massive channel counts that many in the field are proposing. In this talk, I'll discuss an effort in our group to produce a new generation of parametric amplifiers that integrate quantum-limited noise performance with nonreciprocal signal routing.
Excited States in 2D Semiconductors and Heterostructures

JQI Seminars are held on Mondays during Fall and Spring semesters at 11:00 a.m. Eastern Time in Room 2400 of the Atlantic Building. University of Maryland affiliates may participate using Zoom. The seminars are also livestreamed on the JQI YouTube channel (https://www.youtube.com/user/JQInews), which supports audience participation in the chat interface.
Quantum computing with neutral ytterbium atoms
Abstract: Quantum computing with neutral atoms has progressed rapidly in recent years, combining large system sizes, flexible and dynamic connectivity, and quickly improving gate fidelities. The pioneering work in this field has been implemented using alkali atoms, primarily rubidium and cesium. However, divalent, alkaline-earth-like atoms such as ytterbium offer significant technical advantages.
