Exponential Moments of Canonical Phase: Homodyne Measurements
A method for direct sampling of the exponential moments of canonical phase from the data recorded in balanced homodyne detection is presented. Analytical expressions for the sampling functions are shown which are valid for arbitrary states. A numerical simulation illustrates the applicability of the method and compares it with the direct measurement of phase by means of double homodyning.
متن کاملSimultaneous Measurements for Tunable Laser Source Linewidth with Homodyne Detection
The linewidth characteristics of a commercial tunable laser source (TLS) are measured experimentally employing self-homodyne detection method. Three linewidths are obtained at different operating wavelengths with two optical fiber delay lengths. It is found that a slightly higher values are obtained with a longer length of the delay fiber. The long of (50 km and 25 km) of single mode fiber SMF ...
متن کاملIterative tailoring of optical quantum states with homodyne measurements.
As they can travel long distances, free space optical quantum states are good candidates for carrying information in quantum information technology protocols. These states, however, are often complex to produce and require protocols whose success probability drops quickly with an increase of the mean photon number. Here we propose a new protocol for the generation and growth of arbitrary states...
متن کاملNoise characteristics of heterodyne/homodyne frequency-domain measurements.
We theoretically develop and experimentally validate the noise characteristics of heterodyne and/or homodyne measurements that are widely used in frequency-domain diffusive imaging. The mean and covariance of the modulated heterodyne output are derived by adapting the random amplification of a temporal point process. A multinomial selection rule is applied to the result of the temporal noise an...
متن کاملFinite Number of Measurements in Optical Homodyne Tomography
For innnite dimensional quantum systems, there exists no general theory about the eeect of using a nite size ensemble in quantum state measurements. We approach this topic by considering one particular measurement scheme, the optical homodyne tomogra-phy. We deene a measure which tells how well a quantum state, belonging to a preset state space, is determined after N measurements. We illustrate...
