Turn on a quantum switch for improved quantum technology

The second quantum revolution and birth of quantum
information science owes its existence to the superposition of quantum
states. Some dramatic recent results hint at a possible further
revolution in quantum technology, this time harnessing the
superposition of quantum processes. In this talk, I shall discuss some
of the peculiar effects that happen when such superpositions are
created. They span the gamut of usual quantum technologies - from
increasing classical capacity of quantum channels to perfect
teleportation in noisy channels to improved thermometry to universal
quantum computation.
