Integrated quantum photonics
As the field has progressed new quantum algorithms have been developed which provide short and long term routes towards the demonstration of the superiority of quantum computers over their classical counterparts. Cluster state computation is now generally accepted as the approach that will be used to develop a fully fledged quantum computer. Whilst development of quantum computer will require the synthesis of many different aspects of integrated optics, boson sampling seeks to demonstrate the power of quantum computation via technologies readily available and is therefore a very promising near term algorithm to doing so. In fact shortly after its proposal there were several small scale experimental demonstrations of the boson sampling algorithm
Kenji Ohmori
National Institutes of Natural Sciences, Japan (NIMS), Institute for Molecular Science (IMS)Kenji Ohmori has succeeded in designing and visualizing spatiotemporal images given by the interference of matter waves of atoms in a molecule with picometer and femtosecond resolution [1,2]. The precision of this processing is the highest to date, higher than that of the current nanotechnology by three orders of magnitudes. This ultrahigh-precision processing has been implemented with the temporal oscillations of laser electric fields engineered with attosecond precision and imprinted on the matter waves of atoms and electrons in a molecule. He has utilized this technique to develop a molecular computer in which a single 0.3-nanometer-size molecule can calculate 1000 times faster than the current fastest supercomputer [3,4]. He has also developed an ultrafast quantum simulator that can simulate non-equilibrium dynamics of quantum many-body systems in one nanosecond, introducing a novel concept where he has combined his ultrafast coherent control with attosecond precision and ultracold atoms cooled down to temperatures close to absolute zero[5].
