Any quantum measurement is fundamentally a physical interaction between the system being measured and some form of measuring apparatus.

For a quantum measurement, the projectivity is the purity of its pre-measurement state.

These allow the representation of quantum measurements without classical outcomes.

This is a protocol based on quantum measurement.

In the latter part of his career he paid increasing attention to the field of quantum measurements.

Here the questions are going to play the part of quantum measurements.

It might seem that we have now exhausted all possible ways of trying to comprehend quantum mechanical measurement.

Though quantum measurement has peculiarities far more subtle than this, none involves the mind reaching out to change reality.

My brain is definitely going to be stuck on the entanglement of quantum measurements, though.

Mr. Reed said he thought that quantum measurement was the most challenging topic and one where the least amount of research had done.
