What happened
Physicists at the University of Oxford used a hybrid quantum computer built from qubits and quantum oscillators to observe the Aharonov–Bohm effect in a quantum simulation. A later report said the team used quantum interference and trapped-ion qubits to stop a quantum particle from tunneling, using a magnetic field the particle never touched.
Why it matters
The reports describe the work as observing a foundational quantum effect in a new setting.
