For almost a century, Heisenberg's uncertainty principle has stood as one of the defining ideas of quantum physics: a ...

Scientists demonstrated the first entangled measurement for W states, a breakthrough for quantum information transfer and ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...

Although the basic idea of quantum physics dates back to the earliest years of the twentieth century, it wasn’t until 1925, on the German island of Heligoland, that Werner Heisenberg had the ...

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...
