Abstract
We present an operator-algebraic definition for timelike entanglement entropy in CFT. This rigorously defined timelike entanglement entropy is real-valued due to the timelike tube theorem. We further demonstrate why the timelike entanglement entropy should be real-valued from both path integral argument and holography perspective.
