Turing machines are widely believed to be universal, in the sense that any computation done by any system can also be done by a Turing machine. In a new article, researchers present their work ...

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 ...

On Saturday, British mathematician Alan Turing would have turned 100 years old. It is barely fathomable to think that none of the computing power surrounding us today was around when he was born. But ...

As a practising computer scientist, I thought I had a fairly good grasp of Alan Turing’s many contributions to the field. But The Turing Guide, by Jack Copeland, Jonathan Bowen, Mark Sprevak and Robin ...

A few years ago, composer Matthew Suttor was exploring Alan Turing’s archives at King’s College, Cambridge, when he happened upon a typed draft of a lecture the pioneering computer scientist and World ...

For something that has been around since the 1930s and is so foundational to computer science, you’d think that the Turing machine, an abstraction for mechanical computation, would be easily ...

His ideas led to early versions of modern computing and helped win World War II. Yet he died as a criminal for his homosexuality. Overlooked is a series of obituaries about remarkable people whose ...
