The phenomenal success of our integrated circuits managed to obscure an awkward fact: they’re not always the best way to solve problems. The features of modern computers—binary operations, separated ...

We estimate the number of physical qubits and execution time by decomposing an implementation of Shor’s algorithm for elliptic curve discrete logarithms into universal gate units at the logical level ...

Quantum factor: the Paul trap used by Monz and colleagues. (Courtesy: C Lackner/Quantum Optics and Spectroscopy Group, University of Innsbruck) A quantum computer made of five trapped ions has been ...

Factoring a 2048-bit number using Shor’s algorithm, when accounting for error correction, reportedly requires 400,000 qubits. However, it is well known that there ...

As well as being incredibly fascinating, quantum mechanics is also set to revolutionize the fields of information theory and computation. There exist certain problems that could be solved using a ...

Researchers report that they have designed and built a quantum computer from five atoms in an ion trap. The computer uses laser pulses to carry out Shor's algorithm on each atom, to correctly factor ...

"We show that Shor's algorithm, the most complex quantum algorithm known to date, is realizable in a way where, yes, all you have to do is go in the lab, apply more technology, and you should be able ...

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 ...
