Dear All,

As part of the CN1-SPOKE 10 on Quantum Computing, this year too we plan to organize a weekly seminar series.

The first event this year is a talk proposed by by Marilu Chiofalo and Jorge Yago Malo. Title: Analogue and digital quantum simulation: state of the art and opportunities Speaker: Andrew Daley (University of Oxford, UK) Venue: Sala Galilei (room 131, Bldg. C, Department of Physics) Time: Monday, 23/09/2024, 15:00

Abstract: There has been impressive recent progress in developing highly controlled quantum systems, ranging from superconducting qubits to neutral atoms in tweezer arrays. These systems provide a route to medium-scale quantum computing, but also the possibility to build and study models of many-body systems. These range from electrons in solid state physics and materials across to toy models for information spreading in black holes (made possible by long-range interactions). This impressive progress had led to new opportunities for studying basic science, but has also opened pathways towards making quantum simulation useful in solving problems from chemistry, materials and wider fields.

I will give an introduction to the state of the art in these systems, illustrated with our recent theoretical work on fast scrambling of quantum information in systems with long-range interactions. I will also discuss the opportunities and challenges associated with important questions, including (1) To which degree can analogue devices be quantitatively reliable? And (2) when can we use these systems to give us access to useful information that we cannot compute with conventional supercomputers?

Everyone is welcome!
