Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one. In everyday three-dimensional space, that swap only comes in two flavors. Either the ...

A new study by researchers at the Massachusetts Institute of Technology (MIT) now bridges ...

A ball tossed into the air follows a path that classical physics can track with confidence. Shrink that ball down to the size ...

The universe looks like it is mostly empty space. Remove the stars, planets, dust, and gas, and what remains is nothing at ...

Physics No space, no time, no particles: A radical vision of quantum reality If we admit that quantum numbers are the true essence of reality – not particles, space or time – then a surprising and ...

Quantum computers have the potential to solve problems far beyond the reach of today’s fastest supercomputers. But today’s machines are notoriously fragile. The quantum bits, or “qubits,” that store ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin's Broome Bridge in 1843. But in his ...
