“Imagine a computation that produces a new bit of information in every step, based on the bits that it has computed so far. Over t steps of time, it may generate up to t new bits of information in ...

Imagine you’re on a quest to understand the very nature of computation. You’re deep in the wilderness, far from any paths, and inscrutable messages are carved into the trunks of trees all around you — ...

A leader in the field of computational theory is the latest winner of the A. M. Turing Award, sometimes described as the ‘Nobel Prize’ of computer science. Avi Wigderson at the Institute for Advanced ...

The basic mathematics of quantum mechanics will be reviewed for application to quantum computation. Classical physical computation (not with digital circuits) will be discussed, in particular ...
