Synthesis of Quantum Circuits for Linear Nearest Neighbor Architectures

While a couple of impressive quantum technologies have been proposed, they have several intrinsic limitations which must be considered by circuit designers to produce realizable circuits. Limited interaction distance between gate qubits is one of the most common limitations. In this paper, we suggest extensions of the existing synthesis flow aimed to realize circuits for quantum architectures with linear nearest neighbor (LNN) interaction. To this end, a template matching optimization, an exact synthesis approach, and two reordering strategies are introduced. The proposed methods are combined as an integrated synthesis flow. Experiments show that by using the suggested flow, quantum cost can be improved by more than 50% on average.Comment: 14 pages, 11 figures, 3 table

Association of periodontal disease with lifestyle, diabetes mellitus and oral health care practices in an indigenous Bangladeshi population

The present study evaluates the potential association of periodontal diseases among the indigenous "Garo" population in Bangladesh with their lifestyle, diabetes mellitus and routine oral health care practices. Adult males and females of the community were selected for the study. Data were recorded through one to one, face-to-face interview using a set of standard questionnaire. All teeth except the third molars were examined at 6 sites for gingival colour and swelling, bleeding on probing, probing pocket depths (PPD) and clinical attachment level (CAL). Gingival Index (GI) was recorded according to Loe and Silness. The greatest score for each of the 6 sites was used for assessing the PPD and CAL. Of 240 subjects, 64% were female. The mean number of teeth present was 26, and the mean number of affected teeth was 8.9 (PPD ≥3 mm). The mean ± standard deviations of GI, PPD and CAL of the community were 0.43±0.70, 2.34±0.47 and 2.70±0.77 respectively. Betel-leaf was chewed by 75%, 57.5% were tooth brush user and remaining 42.5% used traditional ways. A statistically significant difference in PPD and CAL was found between smokers and non-smokers; tooth-brush users and non-users; diabetics and non-diabetics. PPD and CAL were significantly high among frequent betel-leaf chewers and in older age-group. Without having an access to a professional dentist or part of any oral health care awareness programme, the relatively low prevalence of periodontal diseases can possibly be attributed, in part, to the traditional eating habits of the indigenous "Garo" population
