| Outline of Final Research Achievements |
Standard approach for quantum computation and information process is based on two-level systems, qubits. This research project, however, aims for new quantum information processing based on collective quantum system taking advantage of continuous variable of the field. During the projet term, we obtained a wide variety of results. We proposed a new approach for quantum energy teleportation to overcome the limitation of distance by introducing a squeezed state between a sender (A) and a receiver (B). We also demonstrated real-space imaging of collective nuclear spins by optically detected micro magnetic resonance.
