Challenges & Opportunities for Developing Superconducting Quantum Information Systems

Developing a large scale quantum information processor has become a major industrial challenge over the last few years. Of the many quantum systems available to tackle this challenge, superconducting circuits have shown impressive results thus far and appear to be posed to scale up rapidly. In this presentation, I will discuss some of the challenges associated with developing superconducting circuits for large scale quantum information processors. This includes providing a basic introduction to superconducting qubits, their fabrication, measurement, and coupled operations. I will then explore some of the emerging opportunities for improving, connecting, and expanding these systems for processing quantum information. In particular, I will highlight my group's efforts at the National Institute of Standards & Technology, Boulder, Colorado to develop non-resonant, parametrically induced coupled interactions between transmon-based superconducting quantum bits for providing fast, high fidelity gate operations. Parametric coupling is also important for connecting larger coupled systems ideal for constructing analog quantum simulators.
