From Majorana to Bloch: two ways to generalize the Bloch sphere representation
The paper compares two ways to represent pure qudit states (d>2) geometrically: increasing points via the Majorana representation or using a single point in a higher-dimensional space via the generalized Bloch representation. It derives explicit analytical relations between these methods, providing a formula for the Bloch vector in terms of Majorana points. This allows for studying quantum correlations and reducing parameters in optimization tasks.
