Quantum mechanics provides the physical basis of teleological evolutions
Giuseppe Castagnoli
We show that the quantum computational speedup of quantum algorithms is due to their teleological character, their being evolutions toward a goal (the solution of the problem) with…

Quantum computational speedup and retrocausality
Giuseppe Castagnoli
Involving only the measurements of commuting observables - the problem-setting and the corresponding solution - quantum algorithms should be subject to classical logic. This would…

The physical basis of teleological evolutions
Giuseppe Castagnoli
We show that the sheer existence of a quantum computational speedup logically implies the mutually exclusive or of well-defined causal loops. In each of them, it is as if the probl…
