Optimal 1 → M phase-covariant cloning in three dimensions

Abstract

In this paper, we derive the explicit transformations of the optimal 1 → 3, 4, 5 phase-covariant cloning in three dimensions, and then generalize them to the cases of 1 → M = 3n, 3n + 1, 3n + 2 (n ≥ 1 integer) cloning. The clone fidelities are coincident with the theoretical bounds found.

Extraction of Prospecting Information for Sedimentary-Metamorphic Type Iron Deposit Based on Ziyuan-3 Satellite Data — Taking Xinjiang Taxkorgan Area as an Example

“…Mineralization alteration Information extraction. Remote sensing geologists have done a number of research to reveal how to make full use of the space characteristic of high spatial resolution images, and have obtained some prospecting application effects [11][12] , but little work have been done on the spectral features of the high spatial resolution images in recent 10 years. According to the multi-spectral band setting of ZY3 satellite, we find the iron minerals (containing Fe 3+ ) have strong reflection in band3 (0.63-0.69µm), and relatively low reflection in band1(0.45-0.52µm), band2 (0.52-0.60µm) and band4 (0.76-0.90µm)).…”
