Limitations on quantum dimensionality reduction
... between states, and proofs going via the 2-norm usually do so only for calculational simplicity. However, here we argue that the 2-norm is of interest in its own right, by giving two operational interpretations of this distance measure. 3.1.

Beating the Standard Quantum Limit
... The same is true when measuring one of the observables (say x) on a set of particles prepared with a spread ∆p on the other observable. [In the general case when we are measuring two observables A and B, the lower bound is given by the expectation value of the commutator between the quantum operator ...

... a system by means of its microstate is doomed to fail. Indeed, one can even say that, given any realistic device, the preparation of a specifically chosen microstate is impossible. In order to get around this problem, we turn from the discussion of a single system to that of a set of similar systems ...
