What is the process that turn 0 into 1. In the formal world we achieve this by simple fiat, perhaps according to come rule or function. In a real computer it is achieved by a flow of electrons, which is equivalent to the annihilation of electrons in one place and their creation in another. In quantum mechanics we see it as the continuous rotation of one state into an orthogonal state (the Schrödinger picture).
The fundamental fact is that we are all the same species, we can mate with one another, fall in love and raise children. All the artificial cultural boundaries that do not recognise this fact have to go, the animosities bred of different parochialistic [parochial?] religious notions, ethical and moral beliefs and so on. None of them have any real foundation in human nature.

Feeling a bit cranky but no obvious post-birthday hangover. A grey rainy day. Pleased to see that Pope Francis approves of breast feeding in the Sistine chapel. Philip Pullella

Complex numbers are essential to quantum mechanics first because they are periodic (and so can model the clock and all the other periodic processes in a computer) and because of their arithmetic properties modelling 'interference' by addition and rotation [progression in space-time] by multiplication.

These days I seem to get one good paragraph out of half a joint. The essence of quantum computation's claim to greater power than digital computation is that a Platonically (formally) perfect analogue machine is more powerful because it can transform infinite sets of data in one operation. The atomic process of a digital computer is a one bit operation, p becomes not-p. However the logical proof of the Platonic analogue contention is digital, using point set theory [which includes Boolean algebra] in which all points are orthogonal and uniquely addressed [by real numbers], rather like a Hilbert space of sufficient dimension to represent processes in a continuum
