In this paper we present the design of a super-scalar processor constructed using optoelectronic components interconnected via high-speed free-space optical buses.

Privacy-preserving (PP) applications allow users to perform online daily actions without leaking sensitive information. The PP scalar product (PPSP) is one of the critical algorithms in many private applications. state-of-the-art PPSP schemes use either computationally intensive homomorphic (public-key) encryption techniques, such as Paillier achieve strong security (i.e., 128 b) or random mask...

We present in a simple terms the theory of the factorizing operator introduced recently by Maillet and Sanches de Santos for the spin-1/2 chains. We obtain the explicit expressions for the matrix elements of the factorizing operator in terms of the elements of the Monodromy matrix. We use this results to derive the expression for the general scalar product for the quantum spin chain. We comment...
