Such control is often manifest via a dependence on eatures such as relative phases of incident laser fields. 3. But there are classical analogs (limits?) that show similar dependences. a.

Time-Dependent Perturbation Theory - MSU Physics
... In time-independent perturbation theory, the object was to find the new eigenvalues and eigenstates when a system whose states are known is ‘perturbed’ by adding an additional term to the Hamiltonian. The main trick was to multiply the perturbation operator by λ, and then expand both the states and ...

In 1989, it was realized that FQH states, having a robust topological degeneracy, contain a completely new kind of order - topological order.[5] A whole new theory was developed to describe the topological orders in FQH liquids. (For a review, see Ref. [6].) The Landau’s theory was developed for cla ...

No, in general the two qubits are entangled and cannot be decomposed into the states of the individual qubits. For example, , which is consid ...
