Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

Physicists created a record-breaking Schrödinger's cat with some of the weirdest atoms in physics
The bigger the quantum superposition, the bigger the proverbial Schrödinger's cat. (dennisvdw/iStockphoto/Getty Images) ...
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 ...
Figure 1: This schematic shows a computation performed on a set of qubits. The qubits can occupy a large number of different states, which are depicted as circles. Operations on these qubits evolve ...
Quantum computers are supposed to have abilities far beyond conventional ones, but verifying that they actually do is surprisingly difficult – because checking their results can itself require ...
An experimental realization of one of Einstein’s thought experiments shows that the quantum world is even more complex than previously thought. A particle passes through a single slit and then through ...
