For more than 60 years, Bell's theorem has been the gold standard for demonstrating that quantum mechanics defies the rules ...

Patterns in chaos have been proven, in the incredibly tiny quantum realm, by an international team co-led by UC Santa Cruz physicist Jairo Velasco, Jr. In a new paper published on November 27 in ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

Quantum computing’s edge looked closer after a hard physics problem seemed beyond classical machines. But a new result shows ...

Picture a cat. I’m assuming you’re imagining a live one. It doesn’t matter. You’re wrong either way—but you’re also right. This is the premise of Erwin Schrödinger’s 1935 thought experiment to ...

Physicists have created a system of two connected time crystals, which are strange quantum systems that are stuck in an endless loop to which the normal laws of thermodynamics do not apply. By ...

The famous double slit experiment shows that particles can travel on two paths at the same time -- but only by looking at a lot of particles and analysing the results statistically. Now a ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...
