A variety of quantum circuits have been designed. Most of them assume that arbitrary pairs of qubits can interact. However, several promising implementations of quantum computation rely on a Linear Nearest Neighbor (LNN) architecture, which arranges quantum bits on a line, and allows neighbor interactions only. Therefore, several specific circuits have been designed on an LNN architecture. However,...
Recently much attentions have been paid to quantum circuit design to prepare for the future ldquoquantum computation era.rdquo Like the conventional logic synthesis, it should be important to verify and analyze the functionalities of generated quantum circuits. For that purpose, we propose an efficient verification method for quantum circuits under a practical restriction. Thanks to the restriction,...
In this paper, we propose a new framework to synthesize rapid single flux quantum (RSFQ) logic circuits. In our framework, we construct a virtual cell, which we call "2-AND/XOR," from the RSFQ logic primitives. By using 2-AND/XOR cells, we can successfully adopt the conventional logic design techniques into our framework, and thus we can successfully generate RSFQ circuits in reasonable...
