What would you consider "more interesting physics"? -- Note that this decomposition also allows you to write a quadratic Hamiltonian which has this state as a thermal state (and where the terms in the Hamiltonian are determined by the $\kappa_i$ and $S$). | |
| Jan 19, 2015 at 16:58 | comment | added | RSG | Thank you for your answer, in particular for the last point. Of course, the entropy of the state comes in terms of the Williamson parameters. It is also suggested in your point 2 c. I am still looking, whether there is some more interesting physics hiding behind those parameters. | |
