Quantum Functional System Research Group &
Semiconductor Quantum Information Device Research Team
(TARUCHA-LAB, 樽茶研究室)

We aim at developing novel concepts and electronics bases that can apply for solid-state quantum computation and quantum interface with semiconductor nanostructures. The major task of this group is to demonstrate ability of the solid-state information processing using quantum operations of quantum states and their entanglement in semiconductor and superconductor nanostructures and finally outline a path for the realization of quantum computing. The specific research topics include fundamental physics of quantum coherence, entanglement, spin dynamics and spin correlation and applications to quantum computing including error correction and logical operations, photon-spin quantum interface which can offer quantum memory and relay, and quantum devices capable of the quantum control.
