Universal resource state for One-Way Quantum Computations
A fascinating model for quantum computing, other than the traditional quantum circuit model, is the “one-way” model that is based on simply doing single qubit measurements to a fixed, initial entangled quantum state of many qubits. By feeding back measurement results to control the axis of subsequent measurements, any quantum circuit can be simulated and any quantum computation can be efficiently and universally implemented. The main challenge is thus realization of the necessary initial, entangled state, which has previously required many-body, non-nearest neighbor interactions to realize, such as for the standard cluster state.
