Milburn}, journal={Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences}, year={2003}, volume={361}, pages={1655 - 1674} }

We are currently in the midst of a second quantum revolution The first quantum revolution gave us new rules that govern physical reality. The second quantum revolution will take these rules and use them to develop new technologies. In this review we discuss the principles upon which quantum technology is based and the tools required to develop it. We discuss a number of examples of research programs that could deliver quantum technologies in coming decades including: quantum information…
