Measurement-induced entanglement and teleportation on a noisy quantum processor.

ABSTRACT: Measurement has a special role in quantum theory¹: by collapsing the wavefunction, it can enable phenomena such as teleportation² and thereby alter the 'arrow of time' that constrains unitary evolution. When integrated in many-body dynamics, measurements can lead to emergent patterns of quantum information in space-time^3-10 that go beyond the established paradigms for characterizing phases, either in or out of equilibrium^11-13. For present-day noisy intermediate-scale quantum (NISQ) processors¹⁴, the experimental realization of such physics can be problematic because of hardware limitations and the stochastic nature of quantum measurement. Here we address these experimental challenges and study measurement-induced quantum information p
