The process, known as quantum tunneling, takes place extremely quickly, making it difficult to confirm whether it takes any time at all. (sciencenews.org)
A spooky phenomenon called quantum tunneling lets particles appear in places where they should not be, as if they had burrowed through the space in between. (discovermagazine.com)
Then he recalled Louis de Broglie's discovery that all bodies have a characteristic wavelength which enables them to engage in quantum tunnelling and quantum diffraction. (newscientist.com)
