Bennett's bridge

Bennett's bridge refers to a quantum phenomenon where two or more pathways, each with different potential energy barriers, interfere constructively or destructively, enabling particles like electrons to tunnel through barriers more efficiently than expected. It illustrates how quantum coherence can enhance transport in certain systems, similar to how overlapping waves can amplify or cancel each other. This concept is relevant in designing molecular electronics and understanding quantum tunneling processes, demonstrating how quantum interference can control energy flow at very small scales, leading to potential advancements in nanotechnology and quantum computing devices.
