On distinguishability, orthogonality, and violations of the second law: contradictory assumptions, contrasting pieces of knowledge
... an adequately large number of diverse measurements on separate instances of these preparations.8 They are thus distinguishable, but not in one-shot. They are represented in this case by different, but non-orthogonal, density matrices. On the other hand, two preparation procedures are represented by ...

Space-time description of squeezing
... In our description of squeezing we have used the language of the creation and annihilation operators to facilitate the comparison with the standard description of this effect. However, certain interesting features of the squeezed states of the electromagnetic field are not seen in this representatio ...

Spin States in Graphene Quantum Dots
... The successive spin filling of orbital states is detected by measuring the difference between ground-state energies as a function of a magnetic field. For a magnetic field in-plane of the quantum dot the Zeeman splitting of spin states is measured. The results are compatible with a g factor of 2, an ...

Instead of the non-invertible function β, one considers the function x 7→ (x, β(x)), which is invertible on its range. In its simplest version, the computation proceeds as x 7→ (x, β(x)) 7 ...
