Biological computation running on quantum computation

Biological computation supporting biological phenomena functionally practices the underlying quantum computation indexically, rather than symbolically. An advantage of the indexical operation of quantum computation rests upon a significant reduction of the computational complexity compared with the corresponding classical counterpart running exclusively upon the symbol manipulation. The reduction of the complexity is sought in allowing for the participation of multiple processors running concurrently in a parallel manner. The concurrent distribution of multiple processors operating mutually in an inseparable manner lets each processor regard the rest of the distribution as its own environment. The environment thus formed and detected by each processor may differ from the similar ones appropriated to the other individual participants nearby. Both the individual processor and the corresponding environment turn out to be agential. Quantum computation practiced indexically may serve as a precursor agency apt for both forming Jakob von Uexkull's umwelt towards the environment and making use of James J. Gibson's affordance from the environment. The individual environment to each material participant there is already indexically agential in pulling that participant in.
