Towards Minimal Resources of Measurement-based Quantum Computation
We improve the upper bound on the minimal resources required for measurementbased quantum computation [4, 3, 6]. Minimizing the resources required for this model is a key issue for experimental realization of a quantum computer based on projective measurements. This new upper bound allows also to reply in the negative to the open question presented in [5] about the existence of a trade-off betw...
متن کاملUniversal resources for measurement-based quantum computation.
We investigate which entanglement resources allow universal measurement-based quantum computation via single-qubit operations. We find that any entanglement feature exhibited by the 2D cluster state must also be present in any other universal resource. We obtain a powerful criterion to assess the universality of graph states by introducing an entanglement measure which necessarily grows unbound...

متن کامل1-qubit versus 2-qubit measurement based quantum computing
We present a comprehensive and universal quantum computing model based on 2-qubit measurements (TQC), which embeds trivially in a model based on 1-qubit measurements known as the one-way model (1WQC). One inherits through this embedding a calculus whereby each TQC computing pattern can be put in a standard form where entanglement is done first, then measurement, then local corrections.
متن کاملDistributed Measurement-based Quantum Computation
We develop a formal model for distributed measurement-based quantum computations, adopting an agent-based view, such that computations are described locally where possible. Because the network quantum state is in general entangled, we need to model it as a global structure, reminiscent of global memory in classical agent systems. Local quantum computations are described as measurement patterns....
