That's not quantum tunneling, that's quantum teleportation! :smile:

QC requires a well-isolated system, i.e. little coupling with the environment. But experimentally, that isolation is not perfect of course. However, decoherence can be "overcome" by error correction at the tradeoff of more qubits. In NMR, the spin is controlled via emf tuned at the proper...
