SUMMARY:Validation of Quantum Devices\, Physics Department Colloquium\
 , Matthias Troyer\, Swiss Federal Institute of Technology Zurich
DESCRIPTION:About a century after the development of quantum mechanics
  we have now reached an exciting time where non-trivial devices that m
 ake use of quantum effects can be built. While a universal quantum com
 puter of non-trivial size is still out of reach there are a number com
 mercial and experimental devices: quantum random number generators\, q
 uantum encryption systems\, and analog quantum simulators. In this col
 loquium I will present some of these devices and validation tests we p
 erformed on them. Quantum random number generators use the inherent ra
 ndomness in quantum measurements to produce true random numbers\, unli
 ke classical pseudorandom number generators which are inherently deter
 ministic. Optical lattice emulators use ultracold atomic gases in opti
 cal lattices to mimic typical models of condensed matter physics. Fina
 lly\, I will discuss the devices built by Canadian company D-Wave syst
 ems\, which are special purpose quantum simulators for solving hard cl
 assical optimization problems.
