• Abstract: A new set of $ h(1) \oplus su(2)$ vector algebra eigenstates on the matrix domain is obtained by defining them as eigenstates of a generalized annihilation operator formed from a linear combination of the generators of this algebra which eigenvalues are distributed as the elements of a square complex normal matrix. A combined method is used to compute these eigenstates, namely, the method of exponential operators and that of a system of first-order linear differential equations. We compute these states for all possible combination of generators and classify them in different categories according to a generalized commutation relation as well as according to the value of a characteristic parameter related to the $su(2)$ algebra eigenvalues. Proceeding in this way, we found a subset of generalized vector coherent states in the matrix domain which can be easily separated from the general set of Schr\"odinger-Robertson minimum uncertainty intelligent states. In particular, for a special choice of the matrix eigenvalue parameters we found the so-called vector coherent states with matrices associated to the Heisenberg-Weyl group as well as a generalized version of them, and also a direct connection with the coherent state quantization of quaternions.

We validate our theory with an empirical study of a collection of synthetic and real-world datasets.

  We find a non-trivial class of eigenspectra with the property that the set of quantum covariance matrices corresponding to any eigenspectrum in this class are related by symplectic transformations. We show that all non-degenerate eigenspectra with this property must belong to this class, and that the set of such eigenspectra coincides with the class of non-degenerate eigenspectra.

  We develop a general framework to linearize the von-Neumann equation rendering it in a suitable form for quantum simulations. We show that one of these linearizations of the von-Neumann equation corresponds to the standard case in which the state vector becomes the column stacked elements of the density matrix. A quantum algorithm to simulate the dynamics of the density matrix is proposed.
