The problem is considered of fitting a parametrically defined model in two or three dimensions to observed data, when angular information about the measured data points is available. Gauss-Newton methods based on correct separation of variables are developed. Some numerical results are included.This...
Quantum generative models provide inherently efficient sampling strategies and thus show promise for achieving an advantage using quantum hardware. In this work, we investigate the barriers to the trainability of quantum generative models posed by barren
A universal quantum computer may solve classically intractable problems within areas ranging from many-body physics to quantum chemistry1. There has been impressive experimental progress in developing quantum computers on different architectures2,3,4. Although achieving fault-tolerant computation remains a ...

Also, calculations were needed for surveying (geometry) and for building and for accounting. However, quite a lot of the problems in the RMP are arithmetic puzzles - problems posed just for the fun of solving them! On this page we will look at how the Egyptians of 4000 years ago worked ...
6. First, we put several traffic cones on a flat ground plane (z = 0) uniformly. We then label each cone’s central position on the ground and its peak in the image, as the yellow and green ‘+’ illustrated in Fig. 6a, and record these coordinates \({\tilde x_i}\) and \({...
7. The system can use polar geometry and trigonometry to calculate functions for the virtual beam as, for example, a line, a 2D plane, an ellipse, a sphere, a cone, or other type of object, based on search context. FIG. 4 illustrates a method to compute the function F(Beam) for a...
The model contains information about the material composition within individual voxels/blocks with a size of 125 m3 (5 m × 5 m × 5 m) within the dump, and consists of about 830.000 voxels in total. The following attributes are linked to the voxels: the geometry (x, y, z) in local...
If the two photons correspond to the intersection between the ordinary and extraordinary cones, the emitted state is entangled in polarisation [19]. Then, the manipulation of one of the particles via a unitary transformation gives rise to the generation of any of the four Bell states, which ...
