A new upper bound on the time it takes for an electron to get through a barrier by Quantum Tunneling has been found. They discovered it takes less than 1.8 attoseconds, perhaps 1.8 attoseconds less. They say their experimental results are "in agreement with recent theoretical findings" and "present a compelling argument for instantaneous tunneling". One attosecond is to a second as a second is to 32 billion years.
