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…
The quantum mechanical notion of unobservable causal loop and the anthropic principle
Giuseppe Castagnoli
It can be argued that the ordinary description of the reversible quantum process between two one-to-one correlated measurement outcomes is incomplete because, by not specifying the…
Unobservable causal loops as a way to explain both the quantum computational speedup and quantum nonlocality
Giuseppe Castagnoli
We consider the reversible processes between two one-to-one correlated measurement outcomes which underly both problem-solving and quantum nonlocality. In the former case the two o…
A relational time-symmetric framework for analyzing the quantum computational speedup
Giuseppe Castagnoli, Eliahu Cohen, Artur Ekert +1
The usual representation of quantum algorithms is limited to the process of solving the problem. We extend it to the process of setting the problem. Bob, the problem setter, select…
