Quantum tunneling and the Aharonov-Bohm effect
Although quantum tunneling has been observed on large scales, no one has yet actually measured the tunneling of a single particle until now. Physicists report using an ion trap system to observe the Aharonov-Bohm effect with quantum tunneling. The AB effect demonstrates that a magnetic field inside a confined region can have a measureable impact on a charged particle which never traveled inside the region.
