Minimal sufficient positive-operator valued measure on a separable Hilbert space
Yui Kuramochi
We introduce a concept of a minimal sufficient positive-operator valued measure (POVM), which is the least redundant POVM among the POVMs that have the equivalent information about…

Tradeoff Relation between Information and Disturbance in Quantum Measurement
Tomohiro Shitara, Yui Kuramochi, Masahito Ueda
When we extract information from a system by performing a quantum measurement, the state of the system is disturbed due to the backaction of the measurement. Numerous studies have…

Construction of the least informative observable conserved by a given quantum instrument
Yui Kuramochi
For a quantum measurement process described by a quantum instrument and a system observable corresponding to a positive-operator valued measure (POVM) $\mathcal…
