We present a quench-interferometric framework to probe zero-temperature quantum phase transitions (QPTs), which circumvents the challenging preparation of a many-body ground state, advancing the study of QPTs with experimentally practical quantum simulation techniques and revealing a stimulating interplay between quantum metrology and non-equilibrium many-body physics.
