Mutual Unbiasedness in Coarse-Grained Continuous Variables

Mutual Unbiasedness in Coarse-Grained Continuous Variables
Daniel S. Tasca, Piero Sánchez, Łukasz Rudnicki, Stephen P. Walborn
The notion of mutual unbiasedness for coarse-grained measurements of quantum continuous variable systems is considered. It is shown that while the procedure of “standard” coarse graining breaks the mutual unbiasedness between conjugate variables, this desired feature can be theoretically established...
