A team of researchers from Q-CTRL and IBM says it has achieved a 3,000-fold wall-clock speedup over the best available ...

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 ...

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 ...

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 ...
