The insight that quantum mechanics offers into the nature of matter at the microscopic level has inspired a wide range of technologies reaching into virtually every aspect of modern industrial society. Transistors, lasers, magnetic resonance tomography and atomic clocks are prominent examples of first generation quantum technologies operating with effects from large ensembles of quantum particles. A series of exceptional achievements in theory and experiments indicate that this first “quantum revolution” will not be the last [1-3]. A seemingly trivial switch to addressing the state of individual quantum particles or quasi-particles as well as their correlations and entanglement opens a regime of effects for new technological innovations rooted in the Einstein-Podolsky-Rosen-Paradoxon [4,5]. How does this fundamental concept in quantum physics translate to new technologies? Can "spooky action at a distance" guarantee the security of digital information and communication in the future? Is "ghost imaging" a technique that will address seemingly unsolvable problems in modern optics? What lies behind the terminology "quantum supremacy" in the comparison of classical und quantum computing and where is the quantum approach truly advantageous? The seminar will address these and other questions along with the fundamentals behind modern "second generation" quantum technologies.
