Abstract - Wine has been around for thousands of years and often evokes images of rolling hills and rustic chateaus. Technology is something that is usually not associated with Wine. With industry challenges such as increasing competition, high energy costs, droughts, fires, and labor challenges wineries are turning to technology for help. During this session, we will explore how tank automation technology is being leveraged/evaluated to address challenges in the wine-making process.

Mr. Lucio Hernandez is the Director of Business Intelligence and Production Systems at Jackson Family Wines. He has over 20 years of IT experience in the wine and spirits industry. Lucio has a Bachelor of Science degree in Computer Information Management Systems from California State University Stanislaus (2001). Lucio’s experience includes IT roles as a Business Systems Analyst, Application Developer, Technical Lead, Project Manager, Manager (Financial Systems and Quality Systems).

Quantum Nanophotonics Hardware with Integrated Color Centers

Assistant Professor
ECE, UC Davis, CA

Thu, 11/18/2021

Color centers in wide band gap materials have been prominently studied for applications as quantum bits, quantum light sources, quantum sensors, and spin-photon interfaces. Silicon carbide, in particular, has been an attractive host of color centers due their NIR single photon emission, long spin-coherence times, nonlinear optical properties, and commercial substrate availability. Integration of color centers with nanophotonic devices has been a challenging task, but significant progress has been made with demonstrations up to 120-fold resonant emission enhancement of emitters embedded in photonic crystal cavities. In this talk, I will discuss new geometries for silicon carbide quantum device integration, including waveguides, photonic crystal cavities, and photonic crystal molecules which can be applied in quantum light generation, quantum repeaters, integrated quantum circuits, and quantum simulation. Using the parameters of the state-of-the-art color center-cavity systems, we explore the light and matter interaction using open quantum system modeling [6]. By carefully including the inhomogeneous broadening in emitter frequencies into the Tavis-Cummings-Hubbard model, we explore multi-emitter interactions in coupled cavity arrays evaluating cavity-protection, localization and superfluid phase transition effects. In addition to simulations on classical computers, we turn to NISQ quantum computers for new opportunities in open quantum system modeling.

Marina Radulaski is an Assistant Professor of Electrical and Computer Engineering at the University of California, Davis leading the Quantum Nanophotonics Laboratory. Her academic training includes a Ph.D. in applied physics and a postdoctoral training in electrical engineering at Stanford University, as well as two undergraduate degrees in physics and computer science at the University of Belgrade and Union University in Serbia. Prof. Radulaski has broad international experience in quantum and solid-state physics research performed at Stanford University, ETH Zurich, Lawrence Berkeley National Lab, Hewlett-Packard Labs, Oxford University, the Institute for Quantum Optics and Quantum Information in Vienna, Helmholtz Center Berlin, the Institute of Physics of the Polish Academy of Science, and the Institute of Physics Belgrade. She is a recipient of the NSF CAREER Award 2021, was selected among the Rising Stars in EECS in 2017, and named 30-Under-30 Up and Coming Physicists by the Scientific American in 2012.

Great Impedance Match for Knowledge Transfer:
Amateur Radio as part of Electrical and Computer Engineering Education

Abstract - The amateur radio community is well known for its creativity and ingenuity in their projects constructed with a modest budget and basic laboratory equipment. The Electrical and Computer Engineering (ECE) community is known for its innovation and world-changing impact. When these two communities meet in the world of electrical and computer engineering education, great outcomes await for faculty and students. This presentation talks about how a university makes these connections to help student success. A starting point is to encourage students to take the Federal Communications Commission (FCC) amateur radio examination early on in their college education in order to get exposure to advanced topics in ECE well in advance of when they take courses on the topic. A second initiative is to encourage student creativity to design and implement their own projects, using amateur radio, in formal and informal laboratory settings of the University curriculum. Finally, amateur radio provides a rich set of topics for senior and graduate level project/thesis activity. This presentation will provide examples of how these amateur radio/ECE interactions occur along with specific project examples that demonstrate that amateur radio is still on the forefront of project innovation.

Dennis Derickson, Amateur Radio call sign AC0P, received his BS, MS, and Ph.D. in electrical engineering from South Dakota State University (1981), the University of Wisconsin in Madison (1982) and the University of California in Santa Barbara (1992). His farming background and youth ham radio hobby heavily influenced his career in engineering. He worked on spectrum and network analyzer measurement equipment at Hewlett Packard (HP) in Santa Rosa, CA in the 1980’s. His Ph.D research focused on high-speed optoelectronics. He joined the Electrical Engineering faculty at Cal Poly in 2005 and was department chair from 2010-2020. He is a founding member of the start-up company Insight Photonics Solutions that is commercializing research initiated at Cal Poly. His outreach activities include summer science camps and robotics programs for local schools.

Powering Inaccessible Circuits and Communicating with them through Coupled Inductors

Abstract - The world today is full of unpowered electronic circuits that rely on contactless methods of receiving power and communicating with an external terminal. The most common example is “Tap cards” at points of sale, to pay fares on public transport, and so on. RF tags are increasingly entering warehouses, hospitals, and other inventory collections. Unlike optically scanned barcodes, electronic circuits today contain non-volatile memory and therefore information unique to each tag.

Most of these applications exploit weakly coupled coils to transmit power and data. How this works is not as obvious as it might seem.

I will show the circuit theoretic principles of these near-field links, and a rediscovery of Tesla’s oscillation transformer that leads to self-regulated power delivery through an inductive link that is, within limits, independent of coupling coefficient.

Speaker Bio - Asad Abidi received the BSc degree in Electrical Engineering from Imperial College, London in 1976, and the PhD from the University of California, Berkeley in 1982. He worked at Bell Laboratories, Murray Hill until 1985, and then joined the faculty of the University of California, Los Angeles where he is Distinguished Chancellor’s Professor of Electrical Engineering. With his students he has developed many of the radio circuits and architectures that enable today’s mobile devices.

Among other awards, Professor Abidi has received the 2008 IEEE Donald O. Pederson Award in Solid-State Circuits and the 2012 Best Paper Award from the IEEE Journal of Solid-State Circuits. The University of California, Berkeley’s Department of EECS recognized him as a Distinguished Alumnus in 2015. He was elected Fellow of IEEE in 1996, Member of the US National Academy of Engineering, and Fellow of TWAS, the world academy of sciences.
