Physicists at CERN — home of the Large Hadron Collider — have for the first time made a qubit from antimatter, holding an antiproton in a state of quantum superposition for almost a minute.
This landmark achievement has been performed by scientists working as part of the BASE collaboration at CERN. BASE is the Baryon Antibaryon Symmetry Experiment, which is designed to measure the magnetic moment of antiprotons – in essence, how strongly they interact with magnetic fields.
