Abstract
Qubus computation is a type of quantum information processing (QIP) where computational qubits couple through quantum bus (qubus). Qubus computation are flexible in terms of physical systems, properties and scales. We explore the hybrid nature and distributed nature of qubus computation, which can be considered to be important and essential feature for scalable QIP. As its application, we investigate the characteristics of a quantum repeater protocol based on the quantum bus (qubus) approach for long-distance quantum communication.
