quantum information theory

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

“a programmable system whose repertoire includes all physically possible computations” — Turing.

You will realize that modern computers are not actually capable of all computations—apparently, they can’t make itself.

Therefore, to actually achieve this, we have to make a more general type of computer: a constructor — a universal quantum constructor.
