Quantum Interference in tunneling electron transport?

[jmeisner2812]

Can anyone break down "quantum interference" in the tunneling transport through aromatic organic molecules? The Math is a little fuzzy, but with a few seminal reference or a conceptual description i might be able to wrap my mind lips around this knowledge pop! haha. any help would be appreciated.

I'm assuming that Quantum Interference refers to the interference of the tunneling particle that determines the probability of where it can be located?
