Explore quantum entanglement in quantum matter through a lecture delivered at the International Centre for Theoretical Sciences' centenary celebration of quantum mechanics. Delve into advanced concepts presented by Subir Sachdev during this one-hour discussion that forms part of a broader five-day meeting examining quantum mechanics across multiple disciplines. Learn alongside international scientists gathering to discuss quantum mechanics in its various manifestations, from high energy physics and string theory to quantum computing and mathematics. Participate in this significant scientific event either through invited in-person attendance or via online streaming, with special consideration given to nominated PhD students and postdocs in Mathematics and Physics.
