I've been using the powermethod (since it does not require matrix inversion) for computing the largest eigenvalue but in some cases it is extremely slow probably due the ratio of eigenvalues lamda2/lamda1 being close to 1. Can anyone suggest a better ...
This paper presents a hybrid variational quantum algorithm that finds a random eigenvector of a unitary matrix with a known quantum circuit. The algorithm is based on the SWAP test on trial states generated by a parametrized quantum circuit. The eigenvector is described by a compact set of clas...

To construct computational quantum error models, we consider three aspects: (1) the type of error operators that may occur at a given location, (2) the nature of the mixture of error operators at a given location, and (3) whether the errors at different locations are independent or not. ...

This paper proposes a new gradient-descent algorithm for complex independent component analysis and presents its application to the Multiple-Input Multiple-Output communication systems. Algorithm uses the Lie structure of optimization landscape and toral decomposition of gradient matrix. The theoretical result...
Due to the swift advancement of the Internet of Things (IoT), there has been a significant surge in the quantity of interconnected IoT devices that send and exchange vital data across the network. Nevertheless, the frequency of attacks on the Internet of
THE SINKHORN-KNOPP ALGORITHM: CONVERGENCE AND APPLICATIONS PHILIP A. KNIGHT∗ Abstract. As long as a square nonnegative matrix A contains sufficient nonzero elements, then the Sinkhorn-Knopp algorithm can be used to balance the matrix, that is, to find a diagonal scaling of A that is doubly...
