Abstract: The Cassini-Huygens mission has revealed Saturn’s largest moon Titan to be a remarkably Earth-like world, with a diverse landscape of rivers, lakes and seas, vast dune fields, plains and mountains. Unlike Earth, however, Titan’s visible surface is dominated by solid organic materials at cryogenic temperatures, and altered by the action of liquid methane and ethane.

Abstract - The speed at which quantum entanglement between qubits with short range interactions can be generated is limited by the Lieb-Robinson bound. Introducing longer range interactions relaxes this bound and entanglement can be generated at a faster rate. The speed limit for this has been explicitly found theoretically only for a two-qubit system and under the assumption of negligible single qubit gate time. We seek to demonstrate such a speed limit for entanglement experimentally using two superconducting transmon qubits.

Abstract: 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.
