Researchers have demonstrated that causal relationships between multiple qubit systems across different time steps can be inferred solely through coarse-grained projective measurements without direct intervention. By leveraging pseudo-density matrix formalism, this method proves robust against measurement imprecision and extends quantum causal analysis beyond instantaneous events to dynamic temporal scenarios. This advancement offers a streamlined framework for understanding cause-and-effect structures in complex multi-qubit architectures using standard scattering circuit platforms.
