Quantum and Darwinism
* Quantum Darwinism
* Quantum Darwinism supported
* Quantum Darwinism
Quantum Darwinism explains the transition of quantum systems from the vast potentiality of superposed states to the greatly reduced set of pointer states as a selection process, einselection, imposed on the quantum system through its continuous interactions with the environment.
Quantum Darwinism appears to conform to this algorithm and thus is aptly named:
