| Outline of Final Research Achievements |
The final objective of this research is to develop a new method using quantum measurement theory. Although there have been a lot of experiments with the quantum non-demolition measurements, those experiments are often only for verifying principles of the theory due to their complicated setup, and it is difficult to apply the technologies to actual phase detectors. On the other hand, applying amplification of quantum weak values could bring us relatively simpler system even for precise measurements.
In this research, we aim to experimentally confirm the fundamental part of the method. For this purpose, we construct a simple Michelson interferometer with a pulse laser light source. In addition, we discuss theoretically the performance of actual phase detectors using the methods.
