The original version of this story appeared in Quanta Magazine. Imagine standing on a railway platform watching a trolley go past. A girl on the trolley drops a bright red ball. To her, the ball falls ...

The reference frames from which observers view quantum events can themselves have multiple possible locations at once — an insight with potentially major ramifications. Imagine standing on a railway ...

Technological devices are getting ever smaller, but as they approach the scale at which quantum physics matters, our understanding of how they interact with their environment evaporates. James Millen ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed. When you purchase through links on our site, we ...
