The information theory computational model behind quantum theory. It proposes quantum computers, proposed during the 80s. Theoretically, quantum computers have quantum supremacy, which is exciting. It is a theory that works with counterfactual information.
quantum computer A quantum computer is a computer that uses quantum effects to perform Turing-like computations
quantum supremacy That a quantum computer outperforms all classical computers
universal computer &ldquo;a programmable system whose repertoire includes all physically possible computations&rdquo; &mdash; Turing.
You will realize that modern computers are not actually capable of all computations&mdash;apparently, they can&rsquo;t make itself.
Therefore, to actually achieve this, we have to make a more general type of computer: a constructor &mdash; a universal quantum constructor.
