Dissipative decoherence in the Grover algorithm
... decoherence is treated in the frame of Lindblad equation for the density matrix [15]. A relatively large number of qubits can be reached by using the methods of quantum trajectories developed in [16,17,18,19,20,21,22]. The quantum algorithms studied in [7,8,9,10,12,13, 14] describe quantum and class ...

... Section 11.2, # 38: Show that f (x, y) = xy/|xy| has no limit as (x, y) → (0, 0). If y = x and x → 0+ , then the limit is one. If y = −x and x → 0+ , then the limit is negative one. Therefore, the limit does not exist. Section 11.2, # 44: If f (x0 , y0 ) = 3, what can you say about the limit of f (x ...
