Stockholm, October 7 (Xinhua) — Three US-based scientists – John Clark, Michel Devore, and John Martinis – have been awarded the 2025 Nobel Prize in Physics for their discovery of macroscopic quantum-mechanical tunneling and energy quantization in electric circuits, the Royal Swedish Academy of Sciences announced on Tuesday.

"Their on-chip experiments showed quantum physics in action," the academy said in a statement.

Quantum mechanics allows particles to pass through barriers through a process known as tunneling. Such effects typically disappear when multiple particles are involved.

The laureates' experiments demonstrated that quantum behavior can also manifest itself at the macroscopic level. As the Academy noted, this discovery paves the way for the further development of quantum technologies, including quantum computers, quantum sensors, and quantum cryptography.

“It’s wonderful to be able to celebrate how a century of quantum mechanics continues to yield new surprises,” said Olle Eriksson, chairman of the Nobel Committee for Physics. “It’s also extremely rewarding, since quantum mechanics underlies all digital technology.” –0–
