# A Survey of Finite Algebraic Geometrical Structures Underlying Mutually Unbiased Quantum Measurements

@article{Planat2004ASO, title={A Survey of Finite Algebraic Geometrical Structures Underlying Mutually Unbiased Quantum Measurements}, author={Michel Planat and Haret C. Rosu and Serge Perrine}, journal={Foundations of Physics}, year={2004}, volume={36}, pages={1662-1680} }

The basic methods of constructing the sets of mutually unbiased bases in the Hilbert space of an arbitrary finite dimension are reviewed and an emerging link between them is outlined. It is shown that these methods employ a wide range of important mathematical concepts like, e.g., Fourier transforms, Galois fields and rings, finite, and related projective geometries, and entanglement, to mention a few. Some applications of the theory to quantum information tasks are also mentioned.
