How three pioneers brought the strange rules of the quantum world into our own, winning the 2025 Nobel Prize in Physics.
The world's most prestigious science prize has been awarded. The 2025 Nobel Prize in Physics honors a revolution that started decades ago, bridging the gap between two different realities.
Meet the laureates: John Clarke, Michel H. Devoret, and John M. Martinis. Together, their collective work in the mid-1980s has reshaped our understanding of the universe and paved the way for future technologies.
They were honored for a monumental achievement: observing the strange rules of the quantum world in an electrical circuit large enough to be held. They brought quantum mechanics from the realm of the ultra-small into our macroscopic world.
In our daily lives, a ball can't simply pass through a wall. But in the bizarre quantum world of atoms, particles can. For a long time, these two worlds seemed completely disconnected.
Using specially designed superconducting circuits, the trio conducted a series of elegant experiments. They proved that quantum weirdness wasn't just for individual atoms; it could also emerge in a system of billions of atoms acting as one.
They demonstrated 'quantum tunneling' in a large system. This phenomenon is like a particle becoming a ghost, passing through an energy barrier it classically shouldn't be able to cross. And it happened right inside their circuit.
They also proved 'energy quantization.' Think of it like a staircase versus a ramp. Instead of having any energy value (a ramp), their system could only possess specific, discrete energy levels, like individual steps.
The revelation was stunning, even to the scientists themselves. On hearing the news of his Nobel win, laureate John Clarke said, 'To put it mildly, it was the surprise of my life. I'm completely stunned.'
Their work built a critical bridge between the microscopic quantum world and our familiar classical world. It showed that with clever engineering, the fundamental and often counterintuitive rules of the universe could be witnessed directly.
This wasn't just a fascinating discovery for physicists. It laid the direct, foundational groundwork for one of today's most revolutionary fields: quantum computing.
As one expert, Dr. Malcolm Connolly, noted, their discovery 'laid the foundation for today's superconducting qubits.' Qubits are the building blocks of quantum computers, promising computational power far beyond today's supercomputers.
'It is wonderful to be able to celebrate the way that century-old quantum mechanics continually offers new surprises,' said the Chair of the Nobel Committee. This field remains the foundation of all modern digital technology.
This achievement highlights the collaborative, international nature of science. For instance, laureate Michel H. Devoret has received support from the European Union's prestigious research programs.
On December 10, the trio will receive their awards in Stockholm. The prize includes a gold medal, a diploma, and a shared sum of 11 million Swedish kronor for their paradigm-shifting work.
Thanks to these pioneers, we are on the cusp of a new technological era. From ultra-powerful computing to hyper-sensitive medical sensors, their legacy is the future they helped unlock for us all.
