Optimal quantum measurements for additive information and disturbance measures
Hiroaki Terashima
Additive measures for information and disturbance in quantum measurements of a system are defined from well-known multiplicative measures such as estimation and operation fidelitie…
Local trade-off between information and disturbance in quantum measurements
Hiroaki Terashima
This study confirms a local trade-off between information and disturbance in quantum measurements. It is represented by the correlation between the changes in these two quantities…
Derivative of the disturbance with respect to information from quantum measurements
Hiroaki Terashima
To study the trade-off between information and disturbance, we obtain the first and second derivatives of the disturbance with respect to information for a fundamental class of qua…
Allowed region and optimal measurement for information versus disturbance in quantum measurements
Hiroaki Terashima
We present graphs of information versus disturbance for general quantum measurements of completely unknown states. Each piece of information and disturbance is quantified by two me…
Information, fidelity, and reversibility in general quantum measurements
Hiroaki Terashima
We present the amounts of information, fidelity, and reversibility obtained by arbitrary quantum measurements on completely unknown states. These quantities are expressed as functi…
Information and fidelity in projective measurements
Hiroaki Terashima
In this study, we explicitly calculate information and fidelity of an r-rank projective measurement on a completely unknown state in a d-dimensional Hilbert space. We also show a t…
