Error correction in quantum computers and beyond
Quantum computers introduce a radically new paradigm of information processing and revolutionize our thinking about the world. However, designing and building quantum computers that operate properly even when some of their components malfunction and cause errors is a heroic endeavor. In this talk, I will explain how quantum error correction and the theory of fault tolerance are indispensable to achieve this task. I will also discuss the profound impact of quantum error correction on our understanding of nature, ranging from new insights into quantum many-body physics to fundamental limitations on sensing and computation.
