Quantum many-body systems typically self-thermalize under time-evolution, leading to a state of maximal entanglement allowed by the underlying symmetries. A well known exception is the phenomena of localization in which quenched spatial disorder can lead to non-ergodic behavior. More recently, it has been found that the 'quantum zeno effect' offers an alternate route to impede entanglement growth -- continuously monitoring a system by an external observer destroys entanglement and can lead to a rich variety of non-ergodic states. In this talk, I will present an idea that relates these two distinct ways of obtaining non-thermal states. In particular, I will discuss how a 'space-time rotation' of quantum circuits, that amounts to the interchange of space and time coordinates, maps a system undergoing localization transition to a system that displays entanglement transition due to the quantum Zeno effect.
