Hyperentanglement-enhanced Weak Value Amplification with High-Order Correlation Function

Abstract

By exploiting the hyperentanglement, we propose a new concrete scheme to realize weak value amplification, which can be implemented by N hyperentangled photons along with coincidence detection. Our scheme can optimally increase the amplification factor by a factor of N compared to the usage of N uncorrelated photons, and achieve the Heisenberg limit for the purpose of parameter estimation. We expect our study can inspire a further investigation on the usage of hyperentanglement in weak measurement and quantum metrology.
