Simultaneous minimum-uncertainty measurement of discrete-valued complementary observables
Alexei Trifonov, Gunnar Bjork, Jonas Soderholm
We have made the first experimental demonstration of the simultaneous minimum uncertainty product between two complementary observables for a two-state system (a qubit). A partiall…

Comprehensive experimental test of quantum erasure
Alexei Trifonov, Gunnar Bjork, Jonas Soderholm +1
In an interferometer, path information and interference visibility are incompatible quantities. Complete determination of the path will exclude any possibility of interference, ren…

Unpolarized light in quantum optics
Jonas Soderholm, Gunnar Bjork, Alexei Trifonov
We present a new derivation of the unpolarized quantum states of light, whose general form was first derived by Prakash and Chandra [Phys. Rev. A 4, 796 (1971)]. Our derivation mak…
