The general notions of duality and symmetry act as powerful tools in understanding many-body classical or quantum systems. A particular type of duality, dubbed spacetime duality, due to the interchange of the roles of space and time, has been recently applied to locally interacting quantum lattice models and offers remarkable advantages and insights. These include building solvable models of many-body quantum chaos, toy models of many-body non-unitary dynamics, dynamical phase transitions and quantum computation. The roots of the duality lie in quantum information theory and the notions of operator entanglement, entangling power, multipartite entangled states, and quantum designs play a central role.
This focus workshop will bring together some of the pioneers in the area and will highlight recent progress and future directions in such spacetime dual models. It is an activity of the Center for Quantum Information Theory of Matter and Spacetime, IIT Madras, and the Department of Physics, IIT Tirupati.
