John Clarke, Michel H. Devoret, and John M. Martinis receive the 2025 Nobel Prize in Physics for experiments demonstrating quantum tunneling in macroscopic circuits. Their mid-1980s work laid the foundation for superconducting quantum computers. The laureates expressed great surprise at the award.
New model revives Einstein's idea for universe's origin
Scientists from Spain and Italy have proposed a model that replaces cosmic inflation with gravitational waves as the key force in the universe's early formation. Published in Physical Review Research, the study suggests gravity and quantum mechanics alone can explain the cosmos's structure. This approach draws on a century-old concept linked to Albert Einstein's work.
Ultracold atomic clocks probe quantum effects on time
Scientists have developed highly precise ultracold atomic clocks that could detect how quantum physics influences the flow of time. By cooling atoms to near absolute zero, these devices aim to measure subtle time variations predicted by quantum theory. The research, published in Nature Communications, opens new avenues for testing fundamental physics.
Scientists uncover quantum effect in organic material for efficient solar power

Researchers at the University of Cambridge have discovered a quantum phenomenon in an organic semiconductor, enabling highly efficient light-to-electricity conversion. This breakthrough, involving Mott-Hubbard behavior in the molecule P3TTM, could lead to simpler, cheaper solar panels made from a single material. The finding connects to foundational physics from a century ago and marks the 120th anniversary of physicist Sir Nevill Mott's birth.
