Abstract
Research in quantum information processing technologies has grown exponentially in the last several years. Superconducting devices and circuits have emerged as the most promising candidates for large-scale  quantum electronic chips. The progress and promise offered by quantized electrical circuits and related quantum bits (qubits) was recognized by the Nobel Prize last year (2025). This talk will review the basics of superconducting quantum devices and circuits in the context of quantum information processing, discuss state of the art technologies, and the enormous challenges that remain in using this technology for performing useful tasks. Although the opportunities afforded by quantum technologies are large, quantum decoherence, or quantum state collapse, due to a number of factors, including  material defects and superconducting quasi-particles, and measurement and control errors, have all limited the number of qubits in quantum computers. The anticipated role in quantum research in the coming years of universities versus that of industries will also be discussed.       

Farhan Rana is the Joseph P. Ripley Distinguished Chair Professor of Electrical and Computer Engineering at Cornell University. Farhan received the B.S., M.S. (1997), and Ph.D. (2003) degrees all in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology (MIT). Before starting the Ph.D., he worked at IBM's T. J. Watson Research Center on nanocrystal and quantum dot memory devices. At Cornell University, Farhan runs a research group with a focus on semiconductor photonics, condensed matter physics, quantum technologies, and optical/terahertz spectroscopy. Farhan is currently the Associate Director of the School of Electrical and Computer Engineering at Cornell University and will become the Chair of the School starting in June 2026.
