Sometimes a visually compelling metaphor is all you need to get an otherwise complicated idea across. In the summer of 2001, a Tulane physics professor named John P.

Some computers are easy to spot. Artificial, human-built computers like those found in smartphones and laptops are abstract ...

Those that solve artificially simplified problems where quantum advantage is meaningless. Those that provide no genuine quantum advantage when all costs are properly accounted for. This critique is ...

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 ...

Computer scientist Lance Fortnow writes that by embracing the computations that surround us, we can begin to understand and tame our seemingly random world. Bohr: Algebra is like sheet music. The ...

A proposed method of profoundly enhancing the energy efficiency of wireless networks unfortunately also suffers from being amongst computationally complex problems to solve. But a computer scientist ...
