On creative machines and the physical origins of freedom. Encyclopedia of Mathematics. Bagarello, F. Conversely, every orthonormal basis and every unit vector are understood to correspond to such a measurement and such a state. The brain is both a neurocomputer and quantum computer. Wang, Z. Pothos, E. Instead, the wave function must satisfy more complicated mathematical boundary conditions as it is nonzero in regions outside the well.
