Abstract: A method solves matrix problems and comprises an encoding step, wherein a matrix is transformed into a unitary matrix, by encoding the matrix with a unitary dilation theorem used as an encoding function; then an optical design step, wherein the unitary matrix is translated into a linear optical circuit, then an optical device is formed by the linear optical circuit, single-photon sources at input and single-photon detectors at output; then an analysis step, wherein the optical device is used for solving a problem related to the matrix, by analyzing the output state of the single-photon detectors. A system implements the method.

Abstract: A sliding pull-out shelf comprising a shelf board, a shelf bracket with at least one shelf bracket tang, a pair of vertical supports spaced a predetermined distance apart, a pair of telescopic slider mechanisms, a magnet, and a magnetic anchor. Each telescopic slider mechanism attaches each shelf board side to each shelf bracket. Each shelf bracket is secured to each vertical support with the shelf bracket tang which is inserted into the vertical support vertical slots. Each shelf bracket is secured to each vertical support such that the shelf brackets project horizontally and parallel to each other. The magnetic anchor lies in the same plane as the vertical supports and is located midway between the vertical supports. The magnet is attached to the shelf board and contacts the magnetic anchor when the shelf is fully against the vertical supports.
