Abstract: For a system of N qubits, living in a Hilbert space of dimension d=2N, it is known that there exists d+1 mutually unbiased bases. Different construction algorithms exist, and it is remarkable that different methods lead to sets of bases with different properties as far as separability is concerned. Here we derive four sets of nine bases for three qubits, and show how they are unitarily related. We also briefly discuss the four-qubit case, give the entanglement structure of 16 sets of bases, and show some of them and their interrelations, as examples. The extension of the method to the general case of N qubits is outlined.

The binary oxides with high lanthana contents show an amorphous structure after calcination at 650 °C. At calcination temperatures higher than 1000 °C there is a phase transformation from the amorphous state to the crystalline LaAlO3 with a perovskite structure. The structure of La2O3 is consistent with the hexagonal system; however, some crystalline microdomains with a monoclinic structure were detected by HRTEM. Islands of La2O3 and LaAl11O18 phases were detected at high lanthana concentration in the binary oxide. The modification in the coordination shell of the Al3+ cations due to the interaction with La3+ cations confirms the formation of phases with a perovskite structure and the presence of islands of the LaAl11O18 phase.
