Multiparty correlation measure based on the cumulant
Dong Zhou, Bei Zeng, Zhen‐Peng Xu, Li You · Physical Review A · 2006
We propose a genuine multiparty correlation measure for a multiparty quantum system as the trace norm of the cumulant of the state. The legitimacy of our multiparty correlation measure is explicitly demonstrated by proving it satisfies the five basic conditions required for a correlation measure. As an application we construct an efficient algorithm for the calculation of our measures for all stabilizer states.
