Australian Researchers Devise Fault-Tolerant Quantum Computer

schliz writes "Researchers have devised a theoretical quantum computer that could function even if one in four qubits were missing. The design is claimed to be the first that tolerates both qubit loss and decoherance to this extent. It performs calculations by measuring, rather than manipulating qubits, so there are fewer points of failure."

You are wrong. In both cases you have only probabilistic guarantees of correctness.
