The Nobel Prize successful Physics has been awarded to Greek-American prof John M. Martinis, unneurotic with John Clarke and Michel H. Devoret.

The 3 scientists were recognized for their groundbreaking experiments that revealed macroscopic quantum tunneling and quantized vigor levels successful superconducting circuits—work that laid the instauration for quantum computing, 1 of the astir transformative technologies of the 21st century.

From Berkeley to breakthroughs

This designation traces backmost to Martinis’s formative years arsenic a doctoral student. Born successful 1958, helium pursued his Ph.D. astatine the University of California, Berkeley, nether the supervision of John Clarke, who would aboriginal stock the Nobel with him.

During this time, Martinis collaborated intimately with Clarke and Michel Devoret, past a postdoctoral researcher, to analyse the quantum behaviour of Josephson junctions—tiny superconducting devices susceptible of exhibiting quantum mechanical effects.

In the mid-1980s, their pioneering experiments demonstrated that specified circuits could show unmistakable quantum phenomena connected a macroscopic scale. Their landmark 1985 survey revealed quantized vigor levels successful a instrumentality tiny capable to acceptable successful the thenar of a hand. This enactment provided the archetypal wide grounds of quantum behaviour successful superconducting systems and laid the cornerstone for superconducting quantum technology.

Expanding probe horizons

After completing his Ph.D., John M. Martinis continued his vocation overseas astatine the Commissariat à l’Energie Atomique successful Saclay, France, earlier returning to the United States to articulation the National Institute of Standards and Technology (NIST) successful Boulder, Colorado.

At NIST, helium developed precocious superconducting devices, including ultra-sensitive detectors for X-rays utilizing transition-edge sensors. These innovations illustrated his quality to merge cardinal physics with applicable engineering, a hallmark of his career.

In 2004, Martinis accepted a module presumption astatine the University of California, Santa Barbara, wherever helium held the Worster Chair successful Experimental Physics. His enactment connected superconducting qubits rapidly established him arsenic a planetary person successful quantum research.

Leading the quantum revolution

Martinis’ expertise attracted Google, which successful 2014 recruited him and his squad to pb its ambitious quantum computing program. Five years later, successful October 2019, his radical published a groundbreaking survey successful Nature titled Quantum Supremacy Using a Programmable Superconducting Processor. The insubstantial elaborate however a 53-qubit processor achieved a computation acold beyond the scope of classical supercomputers—the archetypal objection of quantum supremacy.

Although John M. Martinis stepped down from Google successful 2020, helium remained astatine the forefront of quantum innovation. He concisely joined Silicon Quantum Computing successful Australia earlier co-founding Qolab successful 2022. His imaginativeness for the institution is to leverage semiconductor manufacture expertise to manufacture high-quality qubits astatine scale, a measurement helium views arsenic indispensable for gathering applicable quantum computers. Since January 2025, helium has served arsenic Qolab’s Chief Technology Officer, guiding its method direction.

Honors and bequest for Nobel prize victor John Martinis

Beyond the Nobel Prize, Martinis has earned planetary designation for his contributions. He shared the Fritz London Memorial Prize successful 2014 for advances successful low-temperature physics and received the John Stewart Bell Prize successful 2021 for achievements successful quantum accusation science.

Today, John M. Martinis stands arsenic some a Nobel laureate and a visionary scientist. His career—spanning cardinal discoveries, technological innovation, and concern leadership—exemplifies however physics tin thrust transformative advances that reshape the aboriginal of exertion connected a planetary scale.
