Outline of Final Research Achievements |
In the present research, we have succeeded to show that the Weak Value, which has been intensively studied in recent years as a novel physical quantity in quantum mechanics, may be regarded as a local realistic quantity in the typical quantum mechanical particle-wave duality viewpoint. We also derived a new uncertainty relation for the Weak Value, which includes the standard Heisenberg uncertainty relation as a special case. In addition, we have also provided a theoretical model allowing us to examine the validity of precision measurement by using the Weak Measurement, which is a method to obtain the Weak Value by means of conditional quantum measurement. With this, we analyzed some well-known examples of such precision measurement (including the detection of the quantum Hall effect of light) and proved their validity on a firm basis.
