Quantum Physics

Scientists have found “strange quarks” that originated as virtual particles that sprang from nothing

The puzzle of time remains one of the most persistent obstacles to a unified theory of physics

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking what happens when the observer is part of that world

A record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle

Hidden beneath the hills of southern China, the JUNO observatory shows promise in solving neutrino mysteries

Black holes and quantum mechanics present a paradox about the preservation of information

“Quantum echoes” rippling through Google’s quantum computer chip Willow could lead to advances in molecular chemistry and the physics of black holes

The Nobel Prize in Physics for 2025 honors scaled-up quantum physics—while sidestepping controversies swirling around quantum computing

Scientists have revived an ignored area of math to envision a path toward stable quantum computing

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

A survey of more than 1,000 physicists finds deep disagreements in what quantum theories mean in the real world

Federal officials seized 3,000 copies of Scientific American in 1950 in a “red scare” era of attacks on science. The move backfired and offers lessons for today
