Virtual quantum subsystems.
The physical resources available to access and manipulate the degrees of freedom of a quantum system define the set A of operationally relevant observables. The algebraic structure of A selects a preferred tensor product structure, i.e., a partition into subsystems. The notion of compoundness for quantum systems is accordingly relativized. Universal control over virtual subsystems can be achiev...
متن کاملHolonomic quantum computation in subsystems.
We introduce a generalized method of holonomic quantum computation (HQC) based on encoding in subsystems. As an application, we propose a scheme for applying holonomic gates to unencoded qubits by the use of a noisy ancillary qubit. This scheme does not require initialization in a subspace since all dynamical effects factor out as a transformation on the ancilla. We use this approach to show ho...
متن کاملUsing Virtual Subsystems in Project Managementy
Software project management cannot be performed without a suucient understanding of the entire software system. When it comes to making informed project-related decisions, management personnel require a high-level understanding of the entire system and in-depth information on selected components. Unfortunately , many software systems are so complex and/or old that such information is not readil...
متن کاملFlattening Virtual Simulink Subsystems with Graph Transformation
Nowadays embedded systems are often modeled using MATLAB R ©, Simulink R © and Stateflow R © to simulate their behavior and facilitate design space exploration. As design progresses, models are increasingly elaborated by gradually adding implementation detail. An important elaboration is the execution order of the elements in a model. This execution order is based on a sorted list of all semant...
متن کاملTopological protection and quantum noiseless subsystems.
Encoding and manipulation of quantum information by means of topological degrees of freedom provides a promising way to achieve natural fault tolerance that is built in at the physical level. We show that this topological approach to quantum information processing is a particular instance of the notion of computation in a noiseless quantum subsystem. The latter then provides the most general co...
