More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...

Quantum mechanical effects are known to be easily disrupted by disturbances from the surrounding environment, commonly referred to as noise. To minimize these disturbances, physicists often study ...

For more than 40 years, scientists have known that the quantum Hall effect impacts electrons in strong magnetic fields, but it turns out light also follows the fundamental phenomenon.

Thanks to the alternating single-double nature of the bonds, electrons in these orbitals end up delocalized; the differences between the bonds become a bit irrelevant, and the molecule is best viewed ...

A new computational simulation of the early universe has revealed a fundamental, unbreakable geometric limit to the fabric of spacetime, dubbed the "Metric Wall." Discovered by independent physics ...

Senior Research Leader and Deputy Director, Science and Emerging Technology, RAND Europe The unveiling by IBM of two new quantum supercomputers and Denmark’s plans to develop “the world’s most ...

Computer science, at its most fundamental, is all about inputs and outputs. Consider the simple case of multiplying two numbers on a pocket calculator. You punch in some inputs — the specific numbers ...

Scientists have developed a new way to read the hidden states of Majorana qubits, which store information in paired quantum modes that resist noise. The results confirm their protected nature and show ...
