John M. Martinis

On October 23rd, 2019, Martinis and his team published a paper on Nature with title "Quantum supremacy using a programmable superconducting processor", where they presented how they achieved quantum supremacy (hereby disproving the extended Church-Turing thesis) for the first time using a 53-qubits quantum computer. In April 2020, Wired magazine announced that Martinis reportedly resigned from Google after being reassigned to an advisory role.

In 2004 he moved to the University of California Santa Barbara, where he now holds the Worster Chair in experimental physics. In 2014, Martinis' team was hired by Google to build the first useful quantum computer.

Since 2002 he has been working with Josephson-Junction qubits with the aim of building the first quantum computer.

John M. Martinis received his Physics B.S. (1980) and his PhD from the University of California at Berkeley where he began his studies in 1976. During his PhD he investigated the quantum behaviour of a macroscopic variable, the phase difference across a Josephson tunnel junction.

John M. Martinis (born 1958) is an American physicist and professor. In 2014 the Google Quantum A.I. Lab announced that it had hired Martinis and his University of California, Santa Barbara (UCSB) team to build a quantum computer using superconducting qubit.
