The quantum computation revolution and its implications to physics

In the past 30 years, we have witnessed the emergence of a new field - quantum computation science. This development, now viewed as the "second quantum revolution", does not only have potentially remarkable technological implications, but has already completely shifted the way we understand and study physics itself. The interaction with computer science has introduced a new point of view, by which many-body quantum systems are studied through the "computational lens". I will discuss some of the fundamental ideas that have emerged from this fruitful interplay between computer science and physics, including quantum algorithms and their relations to multipartite entanglement, the mind boggling concept of quantum error correction, the remarkable discovery of quantum fault tolerance and robustness of physical systems to noise, and finally, how all this is related to our understanding of the fundamental question of the transition from quantum to classical physics. I will then ask (and ponder about): What next?
