^{} - The term
*instantaneously*in the last sentence may suggest that our formalism is incompatible with Einstein's relativity. That this is not so has been demonstrated in Ref.[10]. The point is that for a relativistic theory the role of time is being played by the Fock-Schwinger "proper time" as a*Floquet*variable. The reader should bear in mind that the EEQT algorithm is explicitly nonlocal: to simulate a history of an individual system integrations over entire space (or space-time) are needed.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

place.
^{} - The operators for different spin directions do not
commute, but this does not contradicts Heisenberg's uncertainty
relations as these deal with statistical ensembles averages, while
here we are describing an
*individual*quantum system. In fact, realizing the chaotic behavior of a quantum state vector, when several noncommuting observables are being simultaneously monitored, can help us to understand the mechanisms of statistical uncertainties.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

configurations:
^{} - There is no good reason why we chose
these configurations - simplicity and beauty are the main reasons
here. Notice that, to enable easy zooming onto the attractor, we
have chosen the orientations in such a way that in each case the
North Pole, with coordinates (0,0,1), of the sphere is occupied by
one of the vertices.

^{} - It is of interest that Born's
probabilistic interpretation of quantum mechanics as well as the
standard formula for quantum mechanical transition probabilities,
can be derived in this way and there is no need of adding it as a
separate postulate.

^{} - In fact, by
using Cayley transform, this relation identifies the space of
unitary matrices with the compactified Minkowski space.
