DESCRIPTION: In recent years\, quantum circuits have emerged as useful eff
 ective models to understand generic quantum many-body dynamics\, and as co
 ncrete platforms for quantum simulation. The most appealing feature of the
 se systems is that\, contrary to generic many-body systems in continuous t
 ime\, the dynamics of quantum circuits are sometimes amenable to analytica
 l treatment. In the talk I will present a fruitful route to achieve this g
 oal based on imposing a duality symmetry between space and time. I will re
 view how this symmetry allows to fully characterise entanglement spreading
  and operator growth and what are its implications on the spreading of qua
 ntum information. I will then show that the duality symmetry\, and the con
 straints it imposes\, can be systematically relaxed while retaining exact 
 solvability.
