User talk:Yama jlac/Weak measurement

The 'Example Kraus operators' section doesn't quite make sense to me, yet. Although I agree at the end that the limit of the POVM elements, as sigma is taken to zero, should be projectors, clearly the lines above are missing some kets! I think there should be an integral in the definitions of M(q) and E(q), to describe a weighted spread of projectors peaked around the average. Geoknee (talk) 03:03, 16 December 2014 (UTC)
