Joint Quantum Seminar - Prof. Jason Cong Wednesday November 16, 2022 Pierce Hall 301 4:00 PM - 6:00 PM Title: “FPGAs, Real-Time Processing, and Quantum Computing” Abstract: An Field Programmable Gate Array (FPGA) is a programmable integrated circuits that one can customize in his/her office/lab to get a dedicated application-specific circuit for his/her own applications with much reduced processing latency and power consumption compared to general-purpose CPUs. In this talk, I shall start with a quick tutorial of the FPGA technology, including its architecture and design flow. Then, I shall give examples how FPGAs are used for real-time processing and control, including recent works on FPGA-based in-vivo calcium image processing and decoding and high-throughput real-time processing for Compact Muon Solenoid (CMS) detector in the Large Hadron Collider at CERN. Next, I shall discuss how FPGAs can be used in quantum computing, such as closed-loop feedback for stabilizing frequency fluctuations and state initialization for the superconducting qubits. Finally, I shall present our latest progress on high-level synthesis (HLS) that supports dataflow programming and latency-insensitive designs. Our goal is to facilitate researchers (e.g. everyone in the HQI community) to efficiently design FPGAs with no or little prior circuit design experience. 10-minute presentation by Marcin Kalinowski begins at 4:00 PM Refreshments begins at 4:15 PM Guest Presentation begins at 4:30 PM Marcin Kalinowski Talk Title: Non-Abelian Floquet Spin Liquids in a Digital Rydberg Simulator Abstract: Understanding topological matter is an outstanding challenge across several disciplines of physical science. Programmable quantum simulators have emerged as a powerful approach to studying such systems. While quantum spin liquids of paradigmatic toric code type have recently been realized in the laboratory, controlled exploration of topological phases with non-abelian excitations remains an open problem. We introduce and analyze a new approach to simulating topological matter based on periodic driving. Specifically, we describe a model for a so-called Floquet spin liquid, obtained through a periodic sequence of parallel quantum gate operations that effectively simulates the Hamiltonian of the non-abelian spin liquid in Kitaev's honeycomb model. We show that this approach, including the toolbox for preparation, control, and readout of topological states, can be efficiently implemented in state-of-the-art experimental platforms. One specific implementation scheme is based on Rydberg atom arrays and utilizes recently demonstrated coherent qubit transport combined with controlled-phase gate operations. ---- GUEST SPEAKER BIO: JASON CONG is the Volgenau Chair for Engineering Excellence Professor at the UCLA Computer Science Department (and a former department chair), with joint appointment from the Electrical and Computer Engineering Department.
