WebChurch-Turing Thesis (SCT), the widespread belief that Turing Machines (TMs) capture all computation, so models of computation more expressive than TMs are impossible. In this paper, we show that SCT reinterprets the original Church-Turing Thesis (CTT) in a way that Turing never intended; its commonly assumed equiva-lence to the original is a myth. WebA Turing machine is a program that controls a tape ... The Church-Turing Thesis claims that every effective method of computation is either equivalent to or weaker than a Turing machine. “This is not a theorem – it is a falsifiable scientific hypothesis. And …

WebApr 5, 2016 · The Church–Turing thesis only concerns itself with what is computable, but not with the efficiency of computation. It is known that Turing machines are not so efficient, though they polynomially simulate classical computers. Quantum computers are believed to be exponentially more efficient than Turing machines.

WebA Turing machine is a theoretical computing machine invented by Alan Turing (1937) to serve as an idealized model for mathematical calculation.
