    What are you supposed to show when you have no data to present?

    Like when you're doing tons of things but it's mostly preparation for experiments and it's not really working so it's slowing experiments down. There's tons to talk about but there's really nothing to show anyone in terms of a powerpoint.

    If a non-commuting measurement is made on a quantum property (like spin), this can be seen as the wavefunction being prepared. So you can't tell if the outcome represents the property, or that the property is prepared. However, if the property is prepared, we can predict the correlation with a...
