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 a measurable phase by traveling around a magnetic flux, even though it never passes through a region where a magnetic field is present.
The result demonstrates how hybrid quantum systems can be used to simulate interactions between matter and gauge fields that become increasingly difficult to model on classical computers. The paper has been published in Nature Physics.
