Photon number phase uncertainty
WebThe photons, ignoring the uncertainty in frequency, will have an uncertainty in its overall phase and number, and assume a known frequency, i.e., = and =. We can substitute these relations into our energy-time uncertainty equation to find the number-phase uncertainty relation or the uncertainty in the phase and photon numbers. WebJan 6, 2024 · The usage of non-Gaussian states to improve the phase sensitivity of interferometers has been studied before. In this paper, we introduce the multiphoton catalysis two-mode squeezed vacuum (MC-TMSV) state as an input of the Mach-Zehnder interferometer (MZI) and study its phase sensitivity with photon-number parity …

WebMay 1, 2016 · Just like position-momentum uncertainty there is a number-phase uncertainty for the EM waves. So although we know what is the mean number of photons that constitutes the beam, we do not know the exact number. On the other hand if your question is about whether one photon can be treated as an EM wave then of course it is yes.
