Tunneling Qubit Operation on a Protected Josephson Junction Array

We discuss a protected quantum computation process based on a hexagon Josephson junction array. Qubits are encoded in the punctured array, which is topologically protected. The degeneracy is related to the number of holes. The topological degeneracy is lightly shifted by tuning the flux through specific hexagons. We also show how to perform single qubit operation and basic quantum gate operations in this system.Comment: 8 pages, 4 figures. The published version in Phys. Rev., A81(2010)01232

A UNIFIED SOLUTION FOR COORDINATION BY TRIGONOMETRIC METHODS

This short essay discusses the application of elementary computation methods for a unified solution of coordination by trigonometry. It means that after computing bearings and distances for establishing rays, coordinates for unfixed point are obtained by using the polar method in the computation process. Description of the basic concept is completed by the algorithm of a computation process being applicable to HT PTA 4000 + 16/SHARP PC 1500A computer written in BASIC language. The software gives a real interactive communication channel between the user and the program. The portable computer can be combined with a KA 160/CE-516P printer. The software also understands special symbois as well as the Greek and the Hungarian alphabets. Each problem is being supplied by a flowchart of the computation process
