Speaker: Jonilyn Yoder Making Artificial Atoms and Operating Them at Temperatures Colder than Space: Fabrication of Superconducting Qubits for Quantum Computing Abstract: Superconducting qubits are a promising candidate for the
fundamental logic element of a quantum information processor. When cooled to milliKelvin temperatures, these lithographically-defined electronic circuits behave as “artificial atoms,” featuring an anharmonic spectrum of quantized energy levels arising from the non-linear inductance of Josephson tunnel junctions. Over the past 20 years, advances in the fabrication, materials, and design of superconducting qubits have led to significant improvements in their coherence time, which is a key metric to characterize their quantum mechanical performance. Such high-coherence superconducting qubits are now being engineered for quantum annealing and gate-based computing applications. In this seminar, I will introduce fundamental terminology and concepts pertaining to quantum computing, describe our work at MIT Lincoln Laboratory to fabricate highcoherence superconducting qubits, and highlight our current work on developing scalable quantum systems using 3D integration.*

Biography: Dr. Jonilyn Longenecker Yoder is a member of the technical staff in the Quantum Information and Integrated Nanosystems Group at MIT Lincoln Laboratory. She leads the development of nanofabrication processes for superconducting-based quantum computing, where her research focuses on the intersection of high-coherence superconducting qubits and systems-level integration. Prior to joining Lincoln Laboratory in 2013, Jonilyn completed her doctoral degree in physical chemistry at Cornell University and her BS in chemistry at Juniata College. *This research was funded in part by the Office of the Director of National Intelligence (ODNI), Intelligence Advanced Research Projects Activity (IARPA) and by the Assistant Secretary of Defense for Research & Engineering under Air Force Contract No. FA8721-05-C-0002.
