Linear-optical programmable quantum router

This paper presents a scheme for linear-optical implementation of a programmable quantum router. Polarization encoded photon qubit is coherently routed to various spatial modes according to the state of several control qubits. In our implementation, the polarization state of the signal photon does not change under the routing operation. We also discuss generalization of the scheme that would allow to obtain signal dependent routing.Comment: 4 pages, 3 figure

Belt conveyor

V této bakalářské práci je navrhnuto konstrukční řešení pásového dopravníku pro přepravu stavební drti a proveden funkční výpočet podle normy ČSN ISO 5048. Bakalářská práce obsahuje i popis jednotlivých částí pásového dopravníku. Tyto části jsou vybrány z katalogů firem, které je vyrábějí. Dále je navržen pohon dopravníku, proveden rozbor možných řešení násypky a pevnostně zkontrolován hnaný buben.There is designed in this bachelor thesis the construction of the belt conveyor for transport of the building crushed material. The functional calculation is performed according to the norm ČSN ISO 5048. The bachelor thesis includes the description of individual parts of the belt conveyor. These parts are chosen from the catalogues of companies that are manufacturing them. Next there is designed the conveyor traction. The analysis of possible solutions of the hopper and the strenght calculation of the idler drum are performed.
