Quantum computing: Logic gateway
Andrew Steane
Abstract
Two groups have created logic gates using pairs of trapped ions. As components of a quantum computer, these gates have the potential to form part of a scaled-up, workable system.
Quantum computing often features in these pages, owing to the lively pace of research in this area. The main aim is to build a large working quantum computer, but the path towards that goal promises to reveal some wonderful physics; subtle and surprising effects are confidently expected, such as quantum error correction.
