Irrational numbers have underpinned quantum mechanics for a century. Removing them could eliminate its strangest features and trigger the biggest upheaval in physics since quantum theory began ...

Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious, because in the world we see ...

My theory may be able to inform us whether these exotic systems can be a way of structuring things so this quantum state could be more permanent," says Buca. The method is a bit like a road map that ...

Quantum mechanics depicts a counter-intuitive reality in which the act of observation influences what is observed — and few can agree on what that means. Everyone has their favourite example of a ...

In July 1925, physicist Werner Heisenberg wrote a letter to Wolfgang Pauli sharing his new ideas about what would eventually become known as quantum theory. A hundred years later, that theory has been ...

The year 2025 marks the 100th anniversary of the birth of quantum mechanics. In the century since the field’s inception, scientists and engineers have used quantum mechanics to create technologies ...
