Quantum information and computation

Measurement-based quantum computing

Measurement-based quantum computing

Quantum information science asks what information processing tasks are possible if single quantum systems are used as elementary carriers of information. The ability to coherently manipulate the state of a quantum system allows for tasks that are thought to be unachievable in the classical context - such as inherently secure transmission of information - or for the efficient solution of computational problems for which no classical efficient algorithm is known. We ask - with methods of mathematical physics - questions of what manipulation of quantum information is possible. A recent emphasis has been to understand the precise computional power of quantum devices.
