John Matthew Martinis[1] (born 1958) is an American physicist and Professor Emeritus of Physics at the University of California, Santa Barbara.[2][3] He led a team to develop a superconducting quantum computer at Google. With the Sycamore processor, they claimed first evidence of quantum supremacy in 2019.
He shared the 2025 Nobel Prize in Physics with John Clarke and Michel Devoret for their joint work on macroscopic quantum phenomena in superconductors.[4]
Early life and education
Martinis's father came to the United States from Yugoslavia, escaping the communist regime.[5] John Matthew Martinis was born in 1958 and was raised in San Pedro, California.[5]
He graduated from the University of California, Berkeley, Martinis received a Bachelor of Science with a major in physics in 1980 and a Doctor of Philosophy in physics in 1987.[6]
During his doctoral studies, he investigated the quantum behaviour of a macroscopic variable, the phase difference across a Josephson tunnel junction.[7][8] His doctorate advisor was John Clarke.[8] During this time, he collaborated with Michel Devoret, a postdoctoral researcher at the time.[8]
In 1985, Clarke, Devoret, and Martinis presented their analysis of microwave pulses that demonstrated the quantum behavior of a Josephson junction.[8] This work would later become the basis for superconducting quantum computing.[8]
Career
He joined the Commissariat à l'Energie Atomique in Saclay, France,[9] for a first postdoc and then the Electromagnetic Technology division at the National Institute of Standards and Technology (NIST) in Boulder, where he worked on superconducting quantum interference devices (SQUIDs) amplifiers.[10][9]
In 2014, the Google Quantum A.I. Lab announced that it had hired Martinis and his team in a multimillion dollar deal to build a quantum computer using superconducting qubits.[11][12]
On October 23, 2019, Martinis and his team published a paper on Nature with title "Quantum supremacy using a programmable superconducting processor",[13] where they presented how they achieved quantum supremacy for the first time using the Sycamore processor, a 53-qubits quantum processor.[14] In April 2020 Martinis resigned from Google after being reassigned to an advisory role.[15][11]
On September 29, 2020, it was announced that Martinis had moved to Australia to join Silicon Quantum Computing, a start-up founded by Professor Michelle Simmons.[16]
