Non-deterministic Turing Machine - Comparison With Quantum Computers

Comparison With Quantum Computers

It is a common misconception that quantum computers are NTMs. It is believed but has not been proven that the power of quantum computers is incomparable to that of NTMs. That is, problems likely exist that an NTM could efficiently solve but that a quantum computer cannot. A likely example of problems solvable by NTMs but not by quantum computers in polynomial time are NP-complete problems.

Famous quotes containing the words comparison with, comparison and/or quantum:

    What is man in nature? A nothing in comparison with the infinite, an all in comparison with the nothing—a mean between nothing and everything.
    Blaise Pascal (1623–1662)

    Blaise Pascal (1623–1662)

    But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.
    Antonin Artaud (1896–1948)
