Complexity theory is a fundamental branch of theoretical computer science that categorises computational problems according to their inherent difficulty and the resources required to solve them. At ...

“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 ...

A new theory could bring a way to make quantum algorithm development less of an accidental process, say scientists. In 2019, Google claimed it was the first to demonstrate a quantum computer ...

Part of “Complexity Theory,” a column on the tangled questions of our technological age. “Addressing algorithmic bias is like hygiene,” she told me. “You don’t brush once, you don’t floss once, you do ...

The mathematics of symmetry, also known as group theory, is widely used as a tool in the solution of complex problems in many areas of theoretical physics, including string theory. A sequence of ...

Recent survey delivers the first systematic benchmark of TSP solvers spanning end-to-end deep learners, hybrid methods and ...

WEST LAFAYETTE, Ind. — In 2019, Google claimed it was the first to demonstrate a quantum computer performing a calculation beyond the abilities of today’s most powerful supercomputers. But most of the ...

Logic gates are the fundamental building blocks of digital computing systems. This is true for both conventional digital computers and future quantum computers; each processes information by moving it ...
