Quantum degrees of polarization
G. Bjork, J. Soderholm, L. L. Sanchez-Soto +4
We discuss different proposals for the degree of polarization of quantum fields. The simplest approach, namely making a direct analogy with the classical description via the Stokes…
Assessing the Polarization of a Quantum Field from Stokes Fluctuation
A. B. Klimov, G. Bjork, J. Soderholm +8
We propose an operational degree of polarization in terms of the variance of the projected Stokes vector minimized over all the directions of the Poincaré sphere. We examine the pr…
Analysis of the generation of photon pairs in periodically poled lithium niobate
Jonas Soderholm, Keiichi Hirano, Shigehiko Mori +2
The process of spontaneous parametric down-conversion (SPDC) in nonlinear crystals makes it fairly easy to generate entangled photon states. It has been known for some time that th…
Quantum polarization properties of two-mode energy eigenstates
Anita Sehat, Jonas Söderholm, Gunnar Björk +3
We show that any pure, two-mode, -photon state with odd or equal to two can be transformed into an orthogonal state using only linear optics. According to a recently suggest…
Quantum limits on phase-shift detection using multimode interferometers
Jonas Soderholm, Gunnar Bjork, Bjorn Hessmo +1
Fundamental phase-shift detection properties of optical multimode interferometers are analyzed. Limits on perfectly distinguishable phase shifts are derived for general quantum sta…
