Recent advances in quantum technologies, including room-temperature quantum operations on quantum bits (“qubits”), suggest the field is rapidly progressing towards practical quantum sensors and computers. However a major challenge remains how to connect these qubits together. Some types of qubits are very small, making it very difficult to get wires in to address them individually. Some other types, like the most advanced superconducting qubits, are very big, making it difficult to put very many of them into a single fridge. I will describe some general approaches to linking qubits together on the micron scale required for practical integration of many qubits, as well as some potential advantages to using magnetic materials as “linkers”. Recent practical demonstrations of linking behavior are creating a new subfield of quantum research based on magnetic excitations, or magnons, entitled Quantum Coherent Magnonics.
About Speaker
Michael E. Flatté received the A.B. degree in physics from Harvard University, Cambridge, MA, USA, in 1988, and the Ph.D. degree in physics from the University of California at Santa Barbara, Santa Barbara, CA, USA, in 1992. He is a Professor at the Department of Physics and Astronomy, The University of Iowa (UI), Iowa City, IA, USA. After his post-doctoral work at the Institute for Theoretical Physics, University of California at Santa Barbara, and the Division of Applied Sciences, Harvard University, he joined the faculty at UI in 1995. He has over 270 publications and ten patents. He has an adjunct appointment as a Professor at the Department of Applied Physics, Eindhoven University of Technology, Eindhoven, The Netherlands. His research interests include optical and electrical control of spin dynamics in materials, novel spintronic devices, quantum sensors, and solid-state realizations of quantum computation. Dr. Flatté is a fellow of the American Association for the Advancement of Science and the American Physical Society.
