The search of an unstructured database amounts to finding one element having a certain property out $N$ elements. classical with oracle checking at time requires on average $N/2$ steps. Grover algorithm for the quantum search, and its unitary Hamiltonian evolution analogue, accomplish asymptotically optimally in $\mathcal{O} (\sqrt{N})$ We reformulate problem as dissipative Markov process actin...

Tip leakage loss introduces major part of losses of the rotor in axial gas turbines. Therefore, the rotor blade tip has a considerable effect on rotor efficiency. To understand the flow physics of the rotor tip leakage, we solve the flow field for different tip platforms (passive flow control) and by considering coolant tip injection (active flow control). Various blade tip configurations s...
