SWEEP A QUBIT TO ENTANGLE STATES AND TO GAUGE ITS ENVIRONMENT

Here we shall demonstrate that the sweep of a Qubit which is coupled to external quantum degrees of freedom such as quantum oscillator degrees of freedom is extremely beneficial for entanglement creation and the gauging of quantum dissipation Recently we succeeded in the derivation of the excact zero temperature transition probability for the dissipative Landau Zener problem 1 The standard i e the non dissipative Landau Zener problem is an exactly solvable textbook example in t
