Researchers have experimentally recreated another fundamental theoretical model from quantum physics, which goes back to the Nobel Prize laureate Werner Heisenberg. The basis for the successful ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, but deep down, it's not. Over enormous timescales, it could suddenly tip ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

According to all the known laws of physics, the Big Bang should have created a Universe consisting of both matter and ...

Some of the most important quantum effects powering today’s technology happen on scales that are almost impossible to see. One such phenomenon, called the Josephson effect, lies at the heart of ...

For bringing quantum effects to a scale once thought impossible, three physicists have won the 2025 Nobel Prize in physics. In the 1980s, John Clarke, Michel Devoret and John Martinis demonstrated the ...

Physicist Paul Davies’s Quantum 2.0: The past, present and future of quantum physics ends on a beautiful note. “To be aware of the quantum world is to glimpse something of the majesty and elegance of ...
