Abstract

摘要

The partial entanglement entropy (PEE) characterizes how much a subset of the region A contribute to the entanglement entropy of A. In some sense it captures the entanglement between the subset and the complement of A. The PEE is a fundamental quantity in quantum information. I will show how the physical requirements can uniquely determine the PEE in Poincare Invariant theories. Then I will show the PEE proposal is a unique solution to all the requirements and compare the results with other proposals for PEE. These results give strong support for the PEE to be a new well defined quantum information quantity.
