Right Decision on Wrong Quantum Tunneling: The 2025 Nobel Prize and the Myth of Macroscopic

AbstractThe 2025 Nobel Prize for quantum tunneling in an electrical circuit andthe 1973 Prize for tunneling phenomena in solids share the same mechanism:tunneling through a thin oxide barrier described by Josephson equations.The 1973 mechanism was correctly monitored as micro. In 2025, thebarrier remains ∼ 10−9 m, the chip remains micro-fabricated, and the particleremains a Cooper pair. Only the external circuit was enlarged.The phenomenon is correct and the mechanism is correct, but the label”Macroscopic Quantum Tunneling” is incorrect. A micro-based tunnelingevent does not become macroscopic by enlarging its wires. The correct termis enlarged micro tunneling.
