The paper presents a new method of conditional combination of quantum systems that takes into account the external environmental conditions. As a practical example of the method presented here, the well-known Bell states are modeled as conditional combination of two q-bits. Analogous approach can be applied in modeling conditional combinations of two and more quantum system sequences.
Paper presents the results in quantum informatics where two or more quantum subsystems are connected. For modelling the links amongst quantum subsystems the quantum quasi-spin is the most important parameter. We derive a quantum quasi-spin from the condition of logical requirement for the unambiguousness of wave probabilistic function assigned into quantum subsystem. With respect to these results we can define information bosons with integer quasi-spin, information fermions with half-integer quasi-spin and information quarks with third-integer quasi-spin. The methodology can be extended to other variants of quasi-spin.
