Imagine creating two particles, separating them by a large distance, and then discovering that measurements performed on them remain correlated more strongly than classical physics appears to allow. That is the basic surprise behind quantum […]

A photon can arrive at a detector as one localized event, yet thousands of photons sent through an interferometer can gradually build a wave-like interference pattern. Electrons, atoms, and even large molecules can produce similarly […]
In everyday life, measurement seems straightforward. A thermometer reveals a temperature that was already there. A ruler tells us the length of an object. A speedometer reports how fast a car is moving. Quantum physics […]
Quantum physics has a reputation for being strange, and that reputation is well deserved. At atomic and subatomic scales, particles can behave like waves, physical quantities come in discrete values, and two separated objects can […]
