Quantum 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

The first antimatter qubit will help search for differences between matter and antimatter

The LHCb experiment has observed a new difference between matter and antimatter in particles called baryons

Physicists are a step closer to using quantum computers for simulations that are beyond the ability of any ordinary computers

The most anticipated particle physics result of recent years is here—but the real news came one week before: the “muon g–2 anomaly” might have never existed

Even how matter exists in the first place is a mystery to physicists

A freak particle physics process could wipe out all galaxies and life—but it’s wildly unlikely

Astronomical amounts of energy could be extracted from black holes—to build a gigantic bomb, for example. Experts have now implemented this principle in the laboratory

Brookhaven National Laboratory is pushing the boundaries of particle physics.

Quantinuum’s 56-bit trapped-ion computer has succeeded in demonstrating randomness in quantum circuits to establish secure, private connections

After netting the world’s highest-paying science award, preeminent theoretical physicist Gerard ’t Hooft reflects on his legacy and the future of physics
