Midcircuit measurements allow the probing of quantum many-body dynamics with spatial and temporal resolution. In this work, the authors discuss how these records can reveal emergent many-body phenomena in space-time.

Is entanglement essential for thermal equilibrium? The authors show that multipartite entanglement controls how rapidly fluctuations are suppressed: increasing entanglement produces exponentially strong typicality in small quantum systems, whereas macroscopic equilibrium emerges even without large-scale entanglement.
