    "abstract": "An entirely quantum mechanical approach to diagonalize hermitean matrices has\nbeen presented recently. Here, the genuinely quantum mechanical approach is\nconsidered in detail for (2x2) matrices. The method is based on the measurement\nof quantum mechanical observables which provides the computational resource. In\nbrief, quantum mechanics is able to directly address and output eigenvalues of\nhermitean matrices. The simple low-dimensional case allows one to illustrate\nthe conceptual features of the general method which applies to (NxN) hermitean\nmatrices.",
