DESCRIPTION:Quantum mechanics exhibits a stark dichotomy between unitary t
 ime-evolution and measurement. These aspects are further contrasted by the
  fact that traditional many-body quantum theory is developed solely based 
 on unitary aspects. In this talk\, I will explore a fruitful synergy that 
 emerges from the interplay between many-body quantum physics and the non-e
 quilibrium quantum dynamics that arises from measurements. In particular\,
  I will show how measurements can be used to circumvent fundamental constr
 aints imposed by unitary dynamics and efficiently prepare a large class of
  topological phases of matter. In addition to discovering a new hierarchy 
 of many-body quantum states unseen in the unitary setup and a surprising c
 onnection to the unsolvability of the quintic polynomial\, our studies als
 o yield practical protocols for quantum processors that led to the first u
 nambiguous observation of non-Abelian anyons.
