Description
We formulated an alternative to quantum mechanics, whose basic starting point is pure information represented by binary sequences, without any reference to space, time, and matter. Defining correlations between the sequences, we derived highly non-trivial QM results: rules of angular momentum addition, quantum harmonic oscillator, Clebsch-Gordan coefficients, and Wigner’s d-matrix formula. These results indicate that we can reduce QM probabilities to simple counting (no Born rule). In this picture, not only spacetime but also particles and fields appear as emergent phenomena. Apparent quantum indeterminism is interpreted as a consequence of incomplete access to the underlying informational structure encoded in the binary sequences. The framework is inherently discrete, and agreement with standard quantum mechanics is obtained only in the continuum limit, corresponding to sequences of infinite length. Consequently, the theory predicts small deviations from quantum mechanics at finite sequence length, which could be tested in high-precision experiments, particularly in quantum optics.
