   Format: MarkdownItexI have added to _[[wave function collapse]]_ its relation to the expression for [[conditional expectation values]] in [[quantum probability]]: [here](https://ncatlab.org/nlab/show/wave+function+collapse#RelationToConditionalExpectationValues) (e.g. [Kuperberg 05, section 1.2](https://ncatlab.org/nlab/show/wave+function+collapse#Kuperberg05), [Yuan 12](https://ncatlab.org/nlab/show/wave%20function%20collapse#Yuan12))

   I have added to wave function collapse its relation to the expression for conditional expectation values in quantum probability: here (e.g. Kuperberg 05, section 1.2, Yuan 12)
