Quantum Computing: What is it, how does it work, and what are the opportunities for microwave engineers?

#mtt #quantum #microwaves

Abstract: Quantum computing offers the potential for an exponential speed-up of certain classes of
computational problems, and, as such, the development of a practical quantum computer has been a field of
intense research over the past two decades. Yet, it is still early in the development of these systems, as we
have just reached the point at which laboratory experiments have shown that quantum computers can
outperform classical computers at certain computational tasks. As such, it is an exciting time in the field,
analogous to the early days of classical computer development. As microwave engineers there is a
tremendous opportunity to contribute to quantum computing, as the control and measurement of most
quantum processors is carried out using microwave techniques. In this talk, I will describe the use of
microwaves in quantum computing, with a focus on the superconducting qubit technology which was used to
show that a quantum computer is capable of post-classical computation. The talk will be geared toward
microwave engineers with no background in quantum computing and will provide a glimpse into the
fundamentals, contemporary system architectures, recent experiments, and, finally, major microwave
challenges that must be overcome if fault tolerant quantum computing is to become a reality. While the
“quantum” aspects of quantum computing will be described, the deeper technical discussion will focus on the
specification and design of the microwave control and measurement systems required to operate these
systems, using Google’s state-of-the-art Sycamore quantum computer as an example. Ongoing research in
scalable control and measurement electronics will also be described.
