A toolbox for measurement based quantum computation on encoded data — •Michael Zwerger¹, Wolfgang Dür¹, and Hans Jürgen Briegel^1,2 — ¹Institut für theoretische Physik, Universität Innsbruck, Österreich — ²Institut für Quantenoptik und Quanteninformation, Innsbruck, Österreich

We propose a toolbox for measurement based quantum computation on encoded data. It consists of small elementary building blocks, which can perform encoding/decoding, a single qubit rotation and a two qubit gate. They can be combined via Bell measurements to achieve resource states that can perform quantum gates on encoded qubits and simultaneously quantum error correction. We also discuss possible realizations of the building blocks and measurement based quantum error correction with present day technology.
