Formulation of Uncertainty Relation Between Error and Disturbance in Quantum Measurement by Using Quantum Estimation Theory

Más información sobre el libro

Focusing on quantum measurement, the thesis explores the relationship between error and disturbance through quantum estimation theory. The author posits that the estimation process, particularly using signals from a photodetector in quantum optical systems, effectively clarifies the bounds of error and disturbance. By formulating these concepts in terms of Fisher information content, the work establishes an upper limit on estimation accuracy and derives the attainable bounds for error and disturbance in quantum measurements.
