Repetitive Ramsey interferometry measurements allow direct sampling of n-point correlation functions of classical qubit noise processes.
Correlated dephasing of two spin qubits near materials isolates rotational symmetry in nonlocal noise correlations, enabling discrimination of s-, d-, and g-wave superconducting gaps and altermagnet types at nanoscale and low frequencies.
