Researchers from the University of Queensland have taken a significant step in the quest to build a quantum computer, creating a light-based quantum circuit capable of basic calculations and ...

They are often gems that provide a new proof of an old theorem, a novel presentation of a familiar theme, or a lively discussion of a single issue. Building on two centuries' experience, Taylor & ...

An extremely simple proof of the K-K-M-S Theorem is given involving only Brouwer's fixed point theorem and some elementary calculus. A function is explicitly given such that a fixed point of it yields ...

Physicists build basic quantum computing circuitMADISON — Exerting delicate control over a pair of atoms within a mere seven-millionths-of-a-second window of opportunity, physicists at the ...

Researchers in Italy have created the first integrated circuit to combine two transistors made from the “wonder material” graphene. By adapting a technique used to fabricate silicon transistors the ...
