paulie.application.fourpoint.fourpoint#
- paulie.application.fourpoint.fourpoint(generators, p, q, r, s)#
Computes the four-point correlator of Pauli strings \(P\), \(Q\), \(R\), and \(S\).
For \(PR,QS \propto L\) where \(L\) is a linear symmetry, this reduces to the average OTOC of \(P\) and \(Q\).
(arXiV: 2502.16404)
- Parameters:
generators (PauliStringCollection) – Generating set of the Pauli string DLA.
p (PauliString) – Pauli string \(P\).
q (PauliString) – Pauli string \(Q\).
r (PauliString) – Pauli string \(R\).
s (PauliString) – Pauli string \(S\).
- Returns:
The four-point correlator of the Pauli strings.
- Return type:
