In a recent paper we have described an optical implementation of a measure-once one-way quantum finite automaton recognizing a well-known family of unary periodic languages, accepting words not in the language with a given error probability. To process input words, the automaton exploits the degree of polarization of single photons and, to reduce the acceptance error probability, a technique of confidence amplification using the photon counts is implemented. In this paper, we show that the performance of this automaton may be further improved by using strategies that suitably consider both the orthogonal output polarizations of the photon. In our analysis, we also take into account how detector dark counts may affect the performance of the automaton.

AbstractHigh resolution images, obtained during July 11, 1991 total solar eclipse, allowed us to estimate the degree of solar corona polarization in the light of FeXIV 530.3 nm emission line and in the white light, as well. Very preliminary analysis reveals remarkable differences in the degree of polarization for both sets of data, particularly as for level of polarization and its distribution around the Sun’s limb.

The Right

On Lord Wavell’s initiative, the Simla Conference was held to discuss the proposal of a new executive council and a new constitution for India after the war. Master Tara Singh represented the Sikh community at the Simla Conference. The Conference failed due to Jinnah’s insistence that the Muslim League alone had the right to nominate Muslim representatives on the Executive Council. The failure of the Conference made the general elections of 1945–6 all the more important. The general elections resulted in a large degree of polarization between the Hindus, Muslims, and Sikhs. The Muslim League got Muslim mandate in favour of Pakistan. The Congress got a mandate of Hindus and a considerable proportion of the Sikhs for independence without partition. The Akalis got support of the large majority of the Sikhs for an independent political entity of the Sikhs. This polarization was of crucial importance for the future.
