By exploiting 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 further investigation on the usage of hyperentanglement in weak measurement and quantum metrology.
