Heisenberg Limited Polarimetry Using Three-Photon Two-Polarization-Mode Fock States
K. Muroo, Yoshitaka Takubo · 2007
Appropriate non-classical photon states, constructed from the two-polarization-mode Fock states, can attain Heisenberg-limited sensitivity in polarimetric measurements. We show that these states can be found as the eigenstates of a Hermitian operator related to the quantum Stokes operators, and provide a particular example of the measurement with the three-photon states.
