... at time t the three terms on the right side of Eq. 共2兲 commute, since they act on different Hilbert spaces. For the same reason any operator under the influence of Alice at time t commutes with all Bob’s operators at the same time. A simple example may help explain this formalism. Consider the situa ...

Introduction to the Bethe Ansatz I
... In 1931 Hans Bethe2 presented a method for obtaining the exact eigenvalues and eigenvectors of the onedimensional (1D) spin-1/2 Heisenberg model, a linear array of electrons with uniform exchange interaction between nearest neighbors. Bethe’s parametrization of the eigenvectors, the Bethe ansatz, ha ...

The bottom line is: crafting a simple intuitive graphical high-level language on the one hand, and performing an axiomatic study which places composition of systems at the forefront on the other hand, are in fact one and the same thing! Our particular focus here is complementarity of quantum observa ...
