Quantum Information : Theory and Applications

The second quantum revolution is unfolding and attracting significant attention. Indeed, these are exciting times as first applications of quantum information and technologies are becoming available. One ambitious long-term goal is a quantum computer on which one can run quantum algorithms such as the Grover search and Shor’s factorization algorithms and outperform their classical counterparts. A slightly more modest application would be optimization tasks, such as optimizing deep neural networks on a quantum processor. However, maintaining the quantum coherence that is at the core of these applications is very challenging, in particular for the near-term devices, such that quantum error correction will be a key element needed to achieve the aforementioned goals. A related complementary application is quantum simulation where one uses a controlled quantum system to simulate another physical system and thus investigate its properties.
