Computational complexity and computability are central themes in theoretical computer science that address the fundamental question of what can be computed and at what cost. Computability theory ...

In computational complexity theory, P and NP are two classes of problems. P is the class of decision problems that a deterministic Turing machine can solve in polynomial time. In useful terms, any ...

A solution to P vs NP could unlock countless computational problems—or keep them forever out of reach. 1. On Monday, July 19, 2021, in the middle of another strange pandemic summer, a leading computer ...

The axiomatic treatment of the computational complexity of partial recursive functions initiated by Blum is extended to relatively computable functions (as computed, for example, by Turing machines ...

NEW YORK, August 16, 2018 - The 2018 Donald E. Knuth Prize will be awarded to Johan Torkel Håstad of the KTH Royal Institute of Technology (Sweden) for his long and sustained record of milestone ...

Linear optics represents one of the best examples for demonstrating quantum physics. It works at room temperatures, and can be observed with relatively simple devices. In linear optics, one studies ...

A striking new proof in quantum computational complexity might best be understood with a playful thought experiment. Run a bath, then dump a bunch of floating bar magnets into the water. Each magnet ...
