International Symposium on Carrier Interactions and Spintronics in Nanostructures

 The symposium was held March 10-12, 2003, at the NTT Atsugi R&D Center in collaboration with New Energy and Industrial Technology Development Organization (NEDO) and Core Research for Evolutional Science and Technology (CREST) sponsored by Japan Science and Technology Corporation (JST).
 Carrier interactions are receiving strong interest due to their possibility for novel and dream devices, such as solid-state quantum computers. Spin is the most important factor determining the carrier interactions in solid-state systems and spin-electronics (spintronics) have been extensively studied. Research on the coherent control of charge and spin has also progressed very rapidly. To further enhancing these studies, this symposium was organized by Dr. Yoshiro Hirayama (Executive Manager) and Dr. Junsaku Nitta (Group Leader) of NTT Basic Research Laboratories especially putting emphasis on carrier interactions and spintronics. NTT Basic Research Laboratories leads these fields, and the symposium aspired to gather leading scientists in these fields and discuss the most recent topics.
 On the 10th, after opening and welcoming remarks by Dr. Sunao Ishihara, Director of NTT Basic Research Laboratories, Prof. D. D. Awschalom (UCSB) and Prof. K. H. Ploog (Paul-Drude Institute) gave plenary lectures on spin manipulation of electrons and nuclears in semiconductors and on ferromagnetic-semiconductor heterostructures, respectively. There were nine oral presentations on nano-materials, heterostructures, and spintronics. And there were 23 poster presentations.
 On the 11th, the 15 oral presentations discussed nano-wires, spin-related phenomena, nanomechanics, nanoprobing, quantum Hall effects, and quantum information processing. Single photon emission was discussed by the Stanford University group and two-qubit operation of superconductor charge qubit was reported from the NEC group.
 On the 12th, there were nine oral presentations on superconductor proximity effects, diluted magnetic semiconductors, and quantum information processing. The first demonstration of a semiconductor charge qubit was reported by an NTT group. There were 24 poster presentations on that day.
 There were totally 162 participants [including 69 from NTT]. All participants greatly enjoyed the high-quality presentations and discussions on carrier interactions and spintronics.
