Measuring unconventional causal structures in monitored dynamics
Hong-Yi Wang, Haifeng Tang, Xiao-Liang Qi
Causality underpins all logical reasoning. However, the causal structure in quantum processes can be far from intuitive, often differing from its classical counterpart in relativit…
Measurement induced scrambling and emergent symmetries in random circuits
Haifeng Tang, Hong-Yi Wang, Zhong Wang +1
Quantum entanglement is affected by unitary evolution, which spreads the entanglement through the whole system, and also by measurements, which usually tends to disentangle subsyst…
Operator Spreading, Duality, and the Noisy Long-Range FKPP Equation
Tianci Zhou, Éric Brunet, Xiaolin Qi
Operator spreading provides a new characterization of quantum chaos beyond the semi-classical limit. There are two complementary views of how the characteristic size of an operator…
Space-time generalization of mutual information
Paolo Glorioso, Xiao-Liang Qi, Zhenbin Yang
The mutual information characterizes correlations between spatially separated regions of a system. Yet, in experiments we often measure dynamical correlations, which involve probin…
