Those who know John Martinis well guess that when he learned he had won the Nobel Prize in Physics, along with fellow physicists John Clarke and Michel Devoret, he simply smiled.
A leading expert in quantum computing, Martinis has worked with Google, and in recent years, he and Michelle Simmons have been striving toward a bold goal: building the first commercially available quantum computer — a challenge far from easy.
His Background
Now 67 years old, Martinis grew up in the United States and studied at the University of California, Berkeley, where John Clarke was his PhD advisor. There, he also met Michel Devoret, with whom he collaborated on research into the quantum behavior of a macroscopic variable.
Over the years, Martinis worked at top research institutions such as CEA Saclay in Paris and the NIST (National Institute of Standards and Technology) in the U.S., where he developed a technique for detecting X-rays.
This involved the use of a superconducting transition-edge microcalorimeter with electrothermal feedback.
The Quantum Dream Begins
In 2002, at the age of 44, Martinis began pursuing the dream of building the first quantum computer. Two years later, he moved to California, becoming a professor of experimental physics at the University of California, Santa Barbara.
This marked the beginning of his rise to the top — a journey filled with hard work and a vision that would eventually need the help of a tech giant to come to life.
The Google Years and Breakthrough
That giant was Google, which approached Martinis ten years later. The Greek-American professor and his team signed a multimillion-dollar agreement with Google to build a quantum computer using superconducting qubits.
With access to cutting-edge technology, Martinis and his team worked tirelessly. In 2019, they achieved what many thought was almost impossible:
They built a quantum computer capable of solving, in just 3 minutes and 20 seconds, a problem that would take a classical supercomputer thousands of years to complete.
Beyond Google
Martinis left Google in 2020, but continued working in quantum mechanics with Clarke and Devoret. He also began collaborating with Michelle Simmons’ company, SQC (Silicon Quantum Computing), aiming to construct the first commercial quantum computer.
“If we can successfully build one,” he said at the time, “it will be a major achievement with a huge impact on humanity.”
Nobel Recognition
Five years later, the persistent Greek-American physicist — whose contribution to the fields of physics and quantum mechanics is recognized worldwide — received the highest honor from the Swedish Academy: the Nobel Prize in Physics, shared with his two long-time colleagues.
