A mathematical model of computation. Named after English scientist Alan Turing, a Turing machine is a finite state machine that reads a tape divided into cells. The Turing machine examines the symbol ...

In 1950, Alan Turing had an answer to that question—a computer was capable of “thought” if its output was so convincing that a person interacting with it couldn ’ t distinguish its answers from those ...

The Church-Turing limit restricts all current computation, including quantum computers, to rational number computation. This is because quantum computer designs (still not scalable even with high ...
