Welcome to the University of Jyväskylä physics colloquium. 

On Friday 10th November at 10 am in FYS1 and Zoom [https://jyufi.zoom.us/j/66703175507] (passcode 890524):
Andreas Norrman, Center for Photonics Sciences, University of Eastern Finland
Quantum Complementarities in Vectorial Light Fields
The principle of complementarity, dictating that quantum systems share mutually exclusive qualities, has had
a major significance for the foundations of physics and even a profound impact on the interpretation of the
fundamental nature of reality [1]. The arguably most recognized manifestation of quantum complementarity
is wave–particle duality, which puts a trade-off for the wave and particle characteristics of a quantum object.
Such duality can be formulated in a quantitative manner in two-way interferometry, stating that “which-path
information” (particle behavior) is complementary to the visibility of intensity fringes (wave behavior) [2].
Photons, however, may exhibit interference not only in the form of intensity fringes but also in the form of
polarization-state fringes, a unique property of vectorial (nonuniformly polarized) light that has to date been
mostly ignored in complementarity contexts. Here we consider implications of such polarization modulation
in the seminal double-slit setup and establish a set of general complementarity relations for quantized vector-
light fields [3–5], revealing several foundational aspects about the dual wave–particle nature of the photon.
