Abstract
The advent of the Noisy Intermediate-Scale Quantum (NISQ) era has sparked renewed interest in understanding how measurements influence the dynamics of coherent quantum systems. Surprisingly, recent discoveries have revealed that this interaction can lead to Measurement-Induced Phase Transitions (MiPTs) [1]. In this talk, I will present new insights into MiPTs [2,3], highlighting three key findings: i) MiPTs can occur even in single-body systems. ii) They are not limited to quantum systems and can arise in classical systems. iii) There is an unexpected connection between MiPTs and surface growth processes.
