Twirl operation

Practical implementations of twirl operations - This paper, reported in 2005 by Anwar and co-workers [20], deals with a practical implementation of a proposal made by Bennett and co-workers in 1996 for the purification of entanglement from a mixed state. The typical situation would be that in which the qubits of an initially pure entangled state rjr ) = ( 01) - 110 V2 are sent through a noisy channel. The twirl operation is a step for the purification. This operation converts an arbitrary mixed state of two qubits into a pseudo-entangled state ... 

This operation is the basis of the party trick in which the joker twirls a bowl of soup around its vertical axis without spilling. The bowl makes two full turns in executing the complete gyration. 

In Reference (Vatin, 2003 and Rodionov, 1985), it is noted that now versatile application of the twirled streams advance process of their research. It leads to thereto that there are many individual highly effective gas-cleaning installations, but their wide eireulation is restrained by absence of accurate recommendations for transition to other produetivity or change of operating modes. Analogous remarks ean be foimd and in other survey research studies on these subjects. 

Except operating conditions, optimum speed of twirl a influences as well design data of the investigated apparatus. In Figure 4.8, dependence of a (0, on diameter of a twirled air swirler is illustrated. 

Empirical dependence for calculation of optimum speed of twirl of the air swirler, considering the direction of rotation of its guide vanes, and also operating conditions of process of clearing of gas emissions is gained.
