Quantum Information Science
Ian A. Walmsley, P. L. Knight · Optics and Photonics News · 2002
Quantum technology has made great strides in recent years. While quantum computers offer many benefits, we are far from seeing them implemented on a mass scale. Here we review the basic building blocks of quantum information processing, identify the advantages of quantum physics over classical physics, explain how quantum communication protocols work and identify the challenges we need to overcome to realize a quantum computer.
