Today's #arXivsummary: https://arxiv.org/abs/2302.04325, by Murciano et. al. Authors study the impact of measurement on an Ising quantum critical chain utilizing correlated ancilla which are entangled with the critical chain and then projectively measured. Measurements can qualitatively alter long-distance correlation. Possible experimental realization in Rydberg arrays. #CondMat #StrEl #arXiv_2302_04325
