Quantum Time: a novel resource for quantum information

Time in relativity theory has a status different from that adopted by standard quantum mechanics, where time is considered as a parameter measured with reference to an external absolute Newtonian frame. This status strongly restricts its role in the dynamics of systems and hinders any formulation to merge quantum mechanics with general relativity, specifically when considering quantum gravity. To overcome those limitations, several authors tried to construct an operator which is conjugate to the Hamiltonian of quantum systems implementing some essential features of the relativistic time. These formulations use the concept of internal or intrinsic time instead of the universal coordinate time used in textbooks. Furthermore, recently it is remarked that the consideration of time with relativistic features could enhance the analysis techniques in quantum information processing and have an impact on its status in causal orders and causal structures of quantum information. The role of clocks, their accuracy and stability has become an important issue in quantum information processing. This article present a substantiative review of recent works which reflect the possibility of utilizing quantum time, measured by quantum clock devised according to Page-Wootters scheme, to stand as a resource for quantum information processing.Comment: 29 pages, 3 figure

DOES BELIEF IN HUMAN EVOLUTION ENTAIL KUFR

© 2020 by the Joint Publication Board of Zygon Nuh Ha Mim Keller, a contemporary Muslim theologian, argues against the compatibility of evolution and Islam. In this article we intend to critically evaluate his position in which he advances three separate arguments. First, he criticizes the science of evolution. Second, he demonstrates the metaphysical problems with naturalism and the role of chance in the enterprise of evolution. Third, he contends that evolution and the creationist narrative in Islamic scripture is irresolvable. Given these points, Keller concludes that believing in human evolution takes one outside the fold of Islam (kufr). After reviewing each of these points we argue that his claims are unwarranted because of other possibilities which Keller may have not considered. In effect, we argue that believing in evolution doesn\u27t necessarily or definitively entail kufr
