2.2.2 Uhlmann’s theorem

Course subject(s) 02. The power of entanglement

In this lecture we explore the relationship between different purifications of the same density matrix.

To follow the lecture, it will be useful to remember that a unitary map from a Hilbert space to itself is any linear map which takes an orthonormal basis for that space to another orthonormal basis.
