Abstract

The one-way model of measurement-based quantum computation [1] is a fascinating alternative to the standard unitary-gate-based circuit model, for qubits as well as for continuous-variable (CV) encodings. Such one-way schemes are realized through single-qubit or single-mode measurements together with outcome-dependent feed-forward operations on a preprepared multi-partite entangled state, the so-called “cluster state”. By choosing an appropriate set of measurement bases on a sufficiently large cluster state, an arbitrary unitary operation can be implemented for the corresponding encoding.
