Decoherence Versus Disentanglement For Two Qubits In A
... where the Schrödinger equation is no longer applicable, or, to put it in a different way, the coherence leaks out of the system into the environment, and, as a result, we have Decoherence. So, Decoherence is a consequence of the inevitable coupling of any quantum system to its environment, causing i ...

Optimal quantum cloning of orbital angular momentum photon
... The overall transferrer fidelity within the output OAM subspace is estimated at Fprep = (0.96 ± 0.01), mainly due to the imperfect mode quality of the q-plates, leading to a non-perfect π → o2 conversion. The polarization and temporal matching on the beam splitter between photons on mode a and b has ...

Three Quantum Algorithms to Solve 3-SAT
... G(|xi1 , . . . , xin i). We recall that linear operators which act on n–registers can be represented as order 2n square matrices of complex entries. Usually (but not in this paper) such operators, as well as the corresponding matrices, are required to be unitary. In particular, this implies that the ...
