| Outline of Final Research Achievements |
We strikingly pointed out the relationship between quantum state tomography and the weak measurement and proposed the experimental protocol and showed its advantage. Furthermore, on the exciton-polariton condensation in the micro cavity system, we studied the high density regime to check the evidence of the Bose-Einstein condensation even in the nonequilibrium situation. Finally, by the generalization of the previous quantum tunneling effect experiment, we pointed out the experimental verifiable protocol to reveal the properties on the identical particles.

| Academic Significance and Societal Importance of the Research Achievements |
本研究成果の学術的意義は、量子トンネル効果と呼ばれている量子力学特有の現象における理論的解釈を深める結果に繋がり、量子現象を実験するという観点から、理論的解釈の妥当性を実験的に検証出来るためのスキームを提示することが出来る。量子トンネル効果がなければ、化学反応プロセスや星形成、宇宙生成に関してまで実験的な検証可能性まで含めた理論体系を構築することが出来ないと考えており、広範囲な科学分野に応用可能であると考えている。
