Self-introduction

From the Office

The office of iTHES assistant, Ms.Chikako Oota is situated at the first floor of the main research building, room # 159. The extension number is 3185. She will be at the office from 10 a.m. to 16 p.m. except on Wednesday.

Upcoming Event

Event report

On Wednesday, March 19, Prof. Matthias Troyer, from the Institut fur Theoretische Physik, ETH Zurich, 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 wall-to-wall.
A recent cover-story of Time magazine was devoted to the first generation of special-purpose quantum analog computers. This subject is attracting considerable attention worldwide. It is now an exciting time where the first non-trivial prototype 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 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 D-Wave 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 non-stop 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).

Takaharu Mori
Self-introduction

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 Generalized-ensemble algorithm, and its application to biomolecules. I'm also interested in parallel computing of molecular dynamics simulations for large-scale 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.
