Abstract: A novel aspect of recent experiments with quantum devices is that measurements can play an active role in preparing the state of the system, not just in diagnosing it. Unlike unitary evolution, the quantum collapse induced by local measurements can have a highly non-local impact on entangled quantum states, instantaneously destroying or creating new long distance correlations. This can lead to surprising collective effects such as measurement induced criticality and new kinds of universal structures in the post-measurement wave-function. I will review recent progress in understanding these phenomena using mappings to effective statistical mechanical models. The post measurement correlations are extremely difficult to observe directly because they are conditioned on the outcome of many-measurements with exponentially small Born probability. I will discuss a way to resolve this post-selection problem by cross-correlating experimental data with results of classical computations.
