Description

Progress in experimental quantum physics has transformed thought experiments into reality, so that an exciting new question can now be asked : How can we harness the "strange" features of quantum mechanics - such as nonlocality, entanglement, and quantum measurement - in new applications ? In this new field, broadly called “quantum technologies”, new ideas and concepts are being put forward.

Today, the most active ones are Quantum metrology, where multiparticle entangled quantum states are employed to improve high-resolution measurements, for example in an atomic clock. Quantum cryptography, where the use of quantum objects (typically photons) as information carriers makes it possible to detect eavesdroppers due to fundamental measurement back-action. Quantum computing, where qubits replace classical bits. For some specific algorithms, “quantum parallelism” can actually lead to a fundamentally faster performance than the best known classical algorithms. Quantum simulations, where a well-controlled quantum system is designed to obey the Hamiltonian of a fundamental problem, often from solid-state physics, which cannot be studied in its original system due to lack of control (impurities, small scale...), nor simulated on a classical computer due to its complexity.

In all of these subjects, the relation between quantum physics and information plays a profound role. The course will tackle fundamental concepts as well as examples. In each lecture, discussion of experiments from various fields (trapped ions, ultracold atoms, superconducting circuits, ...) will complement the theoretical description.
