As microelectronics technology nears the end of exponential growth over time, known as Moore’s law, there is a renewed interest in new computing paradigms such as quantum computing. After many years of fundamental research on superconducting quantum devices, I recently moved my research program to Google with the goal of building a useful quantum computer. Following Feynman’s vision, I will highlight a proof-of-principle experiment to simulate a chemical reaction that finds an interaction cross section. I will also outline a “quantum supremacy” experiment that will demonstrate the exponential power of a quantum processor by checking its output with a classical computer, which is intractable for even the world's most advanced classical supercomputer beyond 45-50 qubits. We are working to perform this experiment in the next year.
John Martinis currently heads the quantum-hardware team at Google. John started the field of research on quantum devices as a graduate student at UC Berkeley in 1985, and has continued this research at NIST Boulder, UC Santa Barbara, and now Google. In 2010 he was awarded the AAAS science breakthrough of the year, and in 2014 was awarded the London Prize for low-temperature physics research.
