More precisely, we present a one to one correspondence between graph theory, and qubit systems, which may be explored to attack qubit information problems using torie geometry considered as a powerful tool to understand modern physics including string theory. Concretely, we examine in some details the cases of one, two, and three qubits, and we find that they are associated with CP1, CP1×CP1 and CP1×CP1× CP1 toric varieties respectively. Using a geometric procedure referred to as a colored toric geometry, we show that the qubit physics can be converted into a scenario handling toric data of such manifolds by help of hypercube graph theory. Operations on toric information can produce universal quantum gates.展开更多

This neural network has a chaotic attractor with two "leaves", each leaf can be regarded as a dynamic process corresponding a feature of the Necker cube. This tentative model suggests another manifestation of the role of chaos in information processing.展开更多

It is well known that there are n disjoint paths connecting any two nodes in an n-dimensional hypercube （n-cube for short）. In order to enhance the performance and reliability, several variants of n-cube networks have been proposed. The enhanced hypercube networks （denoted by Qn,k） is one of these variation. In this paper, its structural natures are obtained in detail and its properties and performance have been analyzed. The minimum transmission delay of enhanced hypercube Qn,k has been proved equal to k ＋q┌n-k＋1/2┐.The one-to-one routing process is also concerned, this paper also proves that＇ thereexists n ＋ 1 internally-disjoint paths between any two distinct nodes in Qn,k for k = 2. It follows that its connectivity and edge-connectivity are n ＋ 1.展开更多
