Hybrid quantum computer observes foundational quantum effect in a new setting

What happened

Physicists in the Department of Physics at the University of Oxford have used a hybrid quantum computer, made up of qubits and quantum oscillators, to observe the Aharonov–Bohm effect in a quantum simulation. The effect is a quantum phenomenon in which a particle can acquire (one company buying another) a measurable phase by traveling around a magnetic flux, even though it never passes through a region where a magnetic field is present.
