Detector Based Evaluation of Extractable Entanglement in Flat spacetime
Hiromasa Tajima, Riku Yoshimoto, Ryo Nemoto +1
Entanglement entropy (EE) is widely used to quantify quantum correlations in field theory, with the well-known result in two-dimensional conformal field theory (CFT) predicting a l…

Entanglement Harvesting from Quantum Field: Insights via the Partner Formula
Yuki Osawa, Yasusada Nambu, Riku Yoshimoto
We examine the condition necessary for extracting entanglement from a quantum field through the use of two local modes A and B (detector modes). We show that Simon's entanglement c…
