Application-Specific Architecture for Quantum Cellular.. - Florin Ciontu Cristian (Correct)
....the mapping of regular problems is described. I. INTRODUCTION Since its initial proposal [1] the quantum cellular automata (QCA) model has received considerable attention in the quest for alternative technologies to CMOS mainly because of its appealing simplicity. However, several studies [5] [6] pointed out serious drawbacks in performance and manufacturability of the metallic or semiconductor cells. Thus, the future of the model QCA appears to rely on a molecular implementation. We are interested in evaluating the implications of those characteristics of the model that are independent ....
....as electron distribution ( 1] 2] magnetic axis ( 4] or magnetic bubble presence ( 3] The nature of the basic interactions is either electrostatic ( 1] 2] or magnetic ( 3] 4] A second issue representative for the QCA model is its sensitivity to geometric positioning. As pointed in [6], very high precision is necessary in cell placement and dot dimensioning in order to ensure proper switching characteristics of the cells. As this reliability degree is very improbable in the hypothesis of molecular implementation, any realistic QCA architecture should incorporate fault ....

.... is to be achieved, the mentioned energy splitting must be at least an order of magnitude larger than kT , which involves severe technological problems, because a large energy splitting requires a strong electrostatic interaction, that, in turn, implies the availability of very small cells [5]. The temperature dependence of the error probability has been computed for a binary wire, for a majority voting gate and for a small combinatorial network: results show a similar behaviour, with a maximum operating temperature for a given error probability that roughly drops logarithmically with ....
