Then, with the scanning tunneling microscope, they were able to observe quantum chaos in action: finally seeing with their own eyes the pattern of electron orbits within the stadium billiard they created in Velasco's lab.

In the real world, no human could survive the unimaginable heat and bone-crushing pressure, even if there were a vehicle capable of tunneling to the core, Vidale said.

Quantum mechanical effects such as radioactive decay, or more generally: 'tunneling', display intriguing mathematical patterns.

And how could he be sure he was tunneling well under the riverbed?

One area of practical application for the research findings is to place limits on how tunneling systems can be used to build qubits for quantum computers.
