DIPC Colloquium: A Quantum Leap in Quantum Information Subtitle: Building Quantum Computers and Quantum Simulators with Cold Atoms and Ions Abstract: On a microscopic scale our world is governed by quantum physics. Apart from fundamental questions and ‘mysteries’ of quantum physics, learning how to control this microscopic world is also an opportunity for new applications and quantum technologies - potentially more powerful than their classical counterparts. In this lecture we discuss recent progress in building quantum computers and quantum simulators. We will focus on quantum optical systems of atoms and ions manipulated by laser light, providing prime examples of quantum systems, which can be controlled on the level of single quanta. This includes a discussion of trapped ions as a universal quantum processor, and digital and analog quantum simulation of strongly correlated quantum matter with atoms in optical lattices. We conclude with an overview of recent theory-experimental work at Innsbruck, discussing topics like variational quantum simulation running on programmable quantum simulators in the ˋInnsbruck quantum cloud´, verification and self-verification of quantum devices, and quantum algorithms for quantum sensing.
