It is a well-known fact that the no-cloning theorem forbids the creation of identical copies of an arbitrary unknown quantum state. In other words, there does not exist a quantum cloning machine that can clone all qua...

The classical adiabatic approximation theory gives an adiabatic approximate solution to the Schr6dinger equation (SE) by choosing a single eigenstate of the Hamiltonian as the initial state. The superposition princi...

Let B(Н) be the algebra of all the bounded linear operators on a Hilbert space Н. For A, P and Q in B(Н), if there exists an operator X ∈ B(Н) such that APXQA = A, XQAPX = X, (QAPX)^* = QAPX and (XQAP)...
