In 1999, Nature published the first demonstration of a superconducting quantum bit, or qubit. This remarkable feat of physics and engineering relied on trillions of atoms to operate in nearly perfect synchrony such that their collective, macroscopic, quantum state was either in 0, 1, or any desired complex superposition of the two.
Twenty years later, superconducting quantum technologies have experienced more than six orders of magnitude in performance improvements and emerged as the leading candidate for a universal quantum computer.
Our colloquium speaker this Monday, Chad Rigetti, CEO and founder of Rigetti Computing, will give insight into their efforts as a Bay-area-based, full-stack quantum computing start-up that has provided 24/7 cloud access to quantum processors since 2017.
He will describe system design considerations and challenges as industry scales up quantum technologies to hundreds of superconducting qubits that are continuously operated at temperatures colder than space, entangled and read out by a complex symphony of radio-frequency control electronics, as well as custom R&D solutions developed to satisfy demands imposed by an rapidly emerging field.
Rigetti’s colloquium, “System Design Considerations for Noisy Intermediate-Scale Quantum Machines,” is scheduled for 3:30 p.m. in Wilson Hall, One West, on Monday, Sept. 16.
Eric Holland is the deputy director of quantum technologies in the Applied Physics and Superconducting Technology Division.
