Quantum computation offers a promising new kind of information processing, where the non-classical features of quantum mechanics are harnessed and exploited. A number of models of quantum computation exist.
These models have been shown to be formally equivalent, but their underlying elementary concepts and the requirements for their practical realization can differ significantly. A particularly exciting paradigm is that of measurement-based quantum computation (MQC), where the processing of quantum information takes place by rounds of simple measurements on qubits prepared in a highly entangled state. In this talk we review recent developments in MQC. We e.g. discuss the role of MQC in understanding the power of quantum computers, the entanglement properties of universal resource states, and connections between MQC and other branches of physics, such as statistical mechanics.
