Query: Fault-tolerant Quantum Computation with Highly Verified Logical Cluster
  States   We investigate a scheme of fault-tolerant quantum computation based on the
cluster model. Logical qubits are encoded by a suitable code such as the
Steane's 7-qubit code. Cluster states of logical qubits are prepared by
post-selection through verification at high fidelity level, where the
unsuccessful ones are discarded without recovery operation. Then, gate
operations are implemented by transversal measurements on the prepared logical
cluster states. The noise threshold is improved significantly by making the
high fidelity preparation and transversal measurement. It is estimated to be
about 3% by a numerical simulation.
