The exploitation of quantum weirdness for computing is one of the great goals of modern physics. It’s promise is dramatic for a wide range of number-crunching tasks. But quantum computers have another trick up their sleeves which is sometimes forgotten–the ability to simulate other quantum systems. Physicists have already shown how quantum computers of various types can simulate phenomenon such as quantum phase transitions and the dynamics of entanglement–things that classical computers simply cannot handle. There is one quantum phenomenon, however, that has never been simulated–tunnelling. This is the ability of quantum particles to cross a barrier without seeming to have passed through it.
