On coexistence and joint measurability of rank-1 quantum observables
arXiv:1308.3154 · doi:10.1088/1751-8113/47/5/052002
Abstract
We show that a rank-1 quantum observable (POVM) M is jointly measurable with a quantum observable M' exactly when M' is a smearing of M. If M is extreme, rank-1 and discrete then M and M' are coexistent if and only if they are jointly measurable.
Theorem 2 of v1 and Example 1 of v2 are incorrect
