We introduce a new type of sparse CSS quantum error correcting code based on the homology of hypermaps. Sparse quantum error correcting codes are of interest in the building of quantum computers due to their ease of implementation and the possibility of developing fast decoders for them. Codes based on the homology of embeddings of graphs, such as Kitaev's toric code, have been discussed widely in the literature and our class of codes generalize these. We use embedded hypergraphs, which are a generalization of graphs that can have edges connected to more than two vertices. We develop theorems and examples of our hypermap-homology codes, especially in the case that we choose a special type of basis in our homology chain complex. In particular, the most straightforward generalization of the m × m toric code to hypermap-homology codes gives us a [(3/2)m²,2, m] code as compared to the toric code which is a [2m²,2, m]code. Thus we can protect the same amount of quantum information, with the same error-correcting capability, using less physical qubits.

Language practitioners the world over have been struggling for professional recognition for many years. In many instances the emphasis has been on establishing measures like legislation to regulate the industry. However, many institutions have also realised that external regulation such as legislation is not enough and that language practitioners in general and text editors specifically needed an internal regulating mechanism. This mechanism was not just something internal to the industry but was more personal, and therefore internal to practitioners themselves. In this regard a properly designed code of ethics was regarded as an indispensable means of setting out to text editors what may be regarded as proper conduct in carrying out their work. No code of ethics for text editors in South Africa exists and text editors who are members of the South African Translators' Association (SATI) subscribe to the code for translators. This is an undesirable state of affairs as it is important for practitioners to feel that a code is specific to them and "belongs" to them in order for them to subscribe to it. More than that, because a code is part of an internal value system it is important for practitioners to internalise such a code for it to be effective. This study, aimed at the design of a code of ethics for text editors, therefore strove to achieve two aims. The first aim was to design a code of ethics for text editors with reference to existing codes in other related fields, gleaning common elements from them. The second aim was to involve a selection of practising text editors in the refinement of the draft code in order to finalise it, thus ensuring that the code would be acceptable to the people most affected by it. The result of the project was the establishment of a code that was acceptable to all the practitioners involved up to the conclusion of the project. This code will be of value in filling the vacuum in this branch of language practice where no ethical guidelines existed before. / Language practitioners the world over have been struggling for professional recognition for many years.
