Generalized polarization measurement and its connection with information energy

Abstract

Abstract We generalize the polarization measurement to the projective measurements of mutually unbiased bases (MUBs). Based on this result, we reveal a direct connection between polarization measurement and information energy function. We also express the polarization measurement by means of symmetric informationally complete positive operator-valued measures (SIC-POVMs). We present an argument suggesting that polarization measurement by means of SIC-POVMs requires fewer resources than the projective measurements of MUBs.
