Event report


On Wednesday, March 19, Prof. Matthias Troyer, from the Institut für Theoretische Physik, ETH Zürich, gave two very exciting talks on testing the first generation of quantum computing devices. Many members of iTHES, as well as researchers from other parts of RIKEN, and from Keio University, attended this talk  attracting about 50 or so people, crowding the seminar room walltowall.
A recent coverstory of Time magazine was devoted to the first generation of specialpurpose quantum analog computers. This subject is attracting considerable attention worldwide. It is now an exciting time where the first nontrivial prototype devices that make use of quantum effects can be built. While a universal quantum computer of nontrivial 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 Prof. Troyer presented some of these devices and also validation tests that his group 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, he discussed the devices built by Canadian company DWave systems, which are special purpose quantum simulators for solving hard classical optimization problems. This last subject is attracting so much attention that the speaker gave a second presentation on this topic, so he stayed in the same seminar room from 2 pm to about 6:30 pm, interacting nonstop with many people, excited about his presentation. Indeed, some members of the audience arrived at 2 pm, the start of his first presentation, and left at around 6:30 pm, the end of his final presentation, not leaving the room (besides some occasional visit to the toilet next door).


Person of the Week
Takaharu Mori
Selfintroduction
I'm Takaharu Mori, a member of the Theoretical Molecular Science
Laboratory. I graduated from the Tokyo University of Science (B.S. and
M.S.) and Nagoya University (Ph.D.), and then came to RIKEN. My main
research area is Biophysics. I'm interested in development of novel
computational and theoretical methods, especially Molecular dynamics
simulation and Generalizedensemble algorithm, and its application to
biomolecules. I'm also interested in parallel computing of molecular
dynamics simulations for largescale supercomputer systems. I hope I can
learn new techniques from other iTHES members and also make good impacts
on activities of the members through the project.
