Abstract: A method of forming coupling interactions between three or more information qubits (3) in a qubit ensemble (5), the method including: coupling the information qubits (3) to each other; coupling each of the information qubits (3) to each of one or more ancilla qubits (9); and controlling the interaction between the information qubits (3) by applying a bias to the one or more ancilla qubits (9), such that the low energy states of the qubit ensemble (5) include three-or-more-body coupling effects between information qubits (3).

Abstract: A software object model for modeling (resource instances and resource types in a network management system. The model comprises object instances and object classes. Each class comprises fragments of data and/or program code and is a generalization of one or more object instances. The model models each resource type by an object class and assigns to the class a class version identifier which indicates at least some capabilities of the resource instance/types and a collection of the fragments included in the class of the version in question. The model further models each resource instance by an object instance of the corresponding class, and assigns to the instance an object instance identifier and an instance version identifier which indicate the version of the class used for modeling the resource type in question.

Abstract: A software object model for modelling resources (resource instances (RI) and resource types (RT)) in a network management system. The model comprises object instances (OI) and object classes (OC). Each class comprises fragments (FG) of data and/or program code and is a generalization of one or more object instances (OI). The model models each resource type (RT) by an object class (OC) and assigns to the class a class version identifier (CVI) which indicates at least some capabilities of the resource (RI, RT) and a collection of the fragments (FG) included in the class (OC) of the version in question. The model further models each resource instance (RI) by an object instance (OI) of the corresponding class, and assigns to the instance (OI) an object instance identifier (OII) and an instance version identifier (IVI) which indicate the version of the class (OC) used for modelling the resource type (RT) in question.
