Abstract

I will discuss the history and prospects for new machines and instruments as anticipated in the newly announced EU Flagship for Quantum Technology. The program of Richard Feynman, as announced almost 60 years ago, to go to the “bottom” in the miniaturization of information-processing technology, has come to fruition, and a set of well-defined technologies, in the areas of quantum computing, quantum simulation, quantum sensing and metrology, and quantum communication, have emerged. I give a perspective on the sometimes abstruse significance of these coming technologies. The scientists will continue beyond these technologies to new unfoldings of quantum knowledge, whose technological significance we can barely fathom today.
