Bayesian estimation in homodyne interferometry

We address phase-shift estimation by means of squeezed vacuum probe and homodyne detection. We analyse Bayesian estimator, which is known to asymptotically saturate the classical Cramér–Rao bound to the variance, and discuss convergence looking at the a posteriori distribution as the number of measurements increases. We also suggest two feasible adaptive methods, acting on the squeezing paramet...

Recent Developments in Homodyne Interferometry

Continuing developments in homodyne laser interferometer systems [1] are improving both their measurement performance capability and their ease of installation. This paper gives an overview of such a system and explains several of the key design features. Firstly, an overview of the optical detection scheme is given. Secondly, a novel method for improving the Sub Divisional Error (SDE) in a Col...

Homodyne Tomography and the Reconstruction of Quantum States of Light

Quantum tomography is a procedure to determine the quantum state of a physical system, or equivalently, to estimate the expectation value of any operator. It consists in appropriately averaging the outcomes of the measurement results of different observables, obtained on identical copies of the same system. Alternatively, it consists in maximizing an appropriate likelihood function defined on t...

Homodyne detection for measuring internal quantum correlations of optical pulses

A new method is described for determining the quantum correlations at different times in optical pulses by using balanced homodyne detection. The signal pulse and sequences of ultrashort test pulses are superimposed, where for chosen distances between the test pulses their relative phases and intensities are varied from measurement to measurement. The correlation statistics of the signal pulse ...

Quantum control of atomic systems by homodyne detection and feedback

We investigate the possibilities of preserving and manipulating the coherence of atomic two-level systems by ideal projective homodyne detection and feedback. For this purpose, the photon emission process is described on time scales much shorter than the lifetime of the excited state using a model based on WignerWeisskopf theory. The backaction of this emission process is analytically described...
