CAMBRIDGE, MA — The most recent email you sent was likely encrypted using a tried-and-true method that relies on the idea that even the fastest computer would be unable to efficiently break a gigantic ...
In 1994, Peter Shor, an American mathematician working at Bell Labs, published a paper with a wonky title and earth-shaking implications. In “Polynomial-Time Algorithms for Prime Factorization and ...
SAN JOSE, Calif., — Scientists at IBM’s Almaden Research Center have performed the world’s most complicated quantum-computer calculation to date. They caused a billion billion custom-designed ...
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 ...
The team implemented the 'phase estimation algorithm' — a central quantum algorithm which achieves an exponential speedup over all classical algorithms. It lies at the heart of quantum computing and ...
