Abstract: Josephson junction based superconducting oscillators have been a critical component for a number of emerging applications that range across quantum computing, communication and sensing.  The power of this one device with its native high frequency oscillator properties can be taken advantage of in both the classical and quantum regime.  This talk discusses some of the basic principles of Josephson based oscillators and some example applications we work on at BBN which span superconducting quantum computing to reservoir computing.

Biography: Thomas Ohki is the Group Lead of Quantum Engineering and Computing at Raytheon BBN Technologies which is focused on development and applications of superconducting devices for quantum information, microwave systems, photonics and beyond CMOS digital technologies. Active research areas include superconducting quantum and neuromorphic computing, as well as superconducting devices hybridized with spintronic and 2-D materials. He has built a world class quantum computing research laboratory in Cambridge, Massachusetts, and superconducting device fabrication capabilities at Raytheon. He holds a Ph.D. in Physics, from the University of Rochester, NY. Prior to joining Raytheon BBN, he held a post-doctoral fellowship at Chalmers University of Technology (Goteburg, Sweden), working on superconducting qubits and superconducting digital logic.
