Abstract :
About a
century after the development of quantum mechanics we have now reached an
exciting time
where
non-trivial devices that make use of quantum effects can be built. While a
universal quantum computer
of
non-trivial size is still out of reach there are a number commercial and
experimental devices:
quantum
random number generators, quantum encryption systems, and analog
quantum simulators.
In this
colloquium I will present some of these devices and validation tests we
performed on them.
Quantum
random number generators use the inherent randomness in quantum measurements to
produce
true
random numbers, unlike classical pseudorandom number generators which are
inherently deterministic.
Optical
lattice emulators use ultracold atomic gases in
optical lattices to mimic typical models of condensed
matter
physics.
Finally, I
will discuss the devices built by Canadian company D-Wave systems, which are
special purpose
quantum
simulators for solving hard classical optimization problems.
