Photon number phase uncertainty
WebWe have experimentally determined all of the quantities involved in the uncertainty relation for the phase and photon number of a mode of the electromagnetic field when the field mode is in a coherent state of small average photon number. This is accomplished by determining the quantum state of the field using optical homodyne tomography, which … WebThe Stokes operators are measured by direct detection [13]. The mode with high photon number âx is used as a phase reference to determine the photon number in the dark mode ây of orthogonal polarization. The S2 and S3 components can be measured by applying appropriate phase shifts between âx and ây and using a balanced photodetector.

Webphase variation is comparable to the time between detec-tions. This can be expected from the results for the single shot case with all photons in one port, where there was a significant improvement in using an adaptive scheme only if the photon number was small. The maximum improvement here is about 24% for N ≈ 4. 10−4 10−2 100 102 104 ...
