The careless use of language in quantum information

An imperative aspect of modern science is that scientific institutions act for the benefit of a common scientific enterprise, rather than for the personal gain of individuals within them. This implies that science should not perpetuate existing or historical unequal social orders. Some scientific terminology, though, gives a very different impression. I will give two examples of terminology invented recently for the field of quantum information which use language associated with subordination, slavery, and racial segregation: 'ancilla qubit' and 'quantum supremacy'.Comment: 2 page

Quantum Cellular Automata

Quantum cellular automata (QCA) are reviewed, including early and more recent proposals. QCA are a generalization of (classical) cellular automata (CA) and in particular of reversible CA. The latter are reviewed shortly. An overview is given over early attempts by various authors to define one-dimensional QCA. These turned out to have serious shortcomings which are discussed as well. Various proposals subsequently put forward by a number of authors for a general definition of one- and higher-dimensional QCA are reviewed and their properties such as universality and reversibility are discussed.Comment: 12 pages, 3 figures.

The simultaneity of complementary conditions:re-integrating and balancing analogue and digital matter(s) in basic architectural education

The actual, globally established, general digital procedures in basic architectural education,producing well-behaved, seemingly attractive up-to-date projects, spaces and first general-researchon all scale levels, apparently present a certain growing amount of deficiencies. These limitations surface only gradually, as the state of things on overall extents is generally deemed satisfactory. Some skills, such as “old-fashioned” analogue drawing are gradually eased-out ofundergraduate curricula and overall modus-operandi, due to their apparent slow inefficiencies in regard to various digital media’s rapid readiness, malleability and unproblematic, quotidian availabilities. While this state of things is understandable, it nevertheless presents a definite challenge. The challenge of questioning how the assessment of conditions and especially their representation,is conducted, prior to contextual architectural action(s) of any kind

Managing change: mental models of SME managers

This study fills some of the gaps in existing studies on organisational change in SMEs by considering the management of change in SMEs in Queensland, Australia, built around the concept of employee participation. First, the paper examines what mental models SME managers espouse in relation to the management of organisational change; and whether small and medium organisations differ in relation to how they manage change. Data was obtained from a state-wide survey of 340 Queensland SME managers, conducted in 2008. The findings confirm the paucity of consultation in Australian workplaces. Within the context of change management, SMEs could benefit from combining their positive views on widespread involvement (including inspiring a shared vision and personally communicating the future vision; communicating the change message repeatedly up and down and across the organisation; and enabling others to act: by energising, empowering, building teams, tangible support with appropriate resources and structures) with a greater degree of ‘actual’ participation from employees in decision making
