A quantum computer has created a strange particle that can remember its past. Quantinuum said Tuesday that its System Model H2 Quantum computer — the highest-performing quantum computer ever built, ...

But such measurements are notoriously challenging: the instruments used are themselves governed by quantum laws, and their interaction with particles can alter the very properties they are meant to ...

Scientists have observed a unique particle that moves easily one way, yet resists at 90 degrees. These semi-Dirac fermions were observed using their energy signature in a topological metal. Particles ...

How many kinds of elementary particles should I say there are? In experiments at the Large Hadron Collider, physicists smash ...
