... obtained by restricting H to the open subset C Reg := T ∗ (Cn )Reg /Sn ,→ C. Thanks to the previous section, the trajectories for H are obtained by projecting those for H. Exercise 12.1. The trajectories for H are of the form (X − tY, Y ). So what remains to prove is that the map C Reg → C induced b ...

Lecture 12: Holevo`s theorem and Nayak`s bound
... The way that Alice chooses to do this is by preparing a quantum register X in some way, depending on A, after which X is sent to Bob. Specifically, let us suppose that {ρ a : a ∈ Σ} is a collection of density operators in D (X ), and that Alice prepares X in the state ρ a for whichever a ∈ Σ is the ...

This can be thought as a filter that ensures photons coming out of it are only of the right polarization. — In-class demonstration with polarizer filter ...
