| Outline of Final Research Achievements |
Nakahara conducted research on high-precision implementation of quantum gates. He also analyzed formation of a vortex in BEC with Ohmi. The vortex phase is imprinted in terms of the Berry phase, where non-adiabatic quantum control has been fully employed to attain high efficiency. The method can be applied more than ten times to pump the vortex phase to create a vortex with a huge winding number. Maruyama conducted research on quantum control of a physical system under restricted access. Nic Chormaic conducted experiments on quantum coherence, switching of several photons and tractor beam by making use of atoms trapped by a nano-optical fiber. Busch studied the phase separation of a BEC under nontrivial geometric configurations, rotating superfluid, non-adiabatic formation of an arbitrary spatial superposition state of a single atom, and application of adiabatic passage to nonlinear physical systems.
