The attempts to discover a theoretical structure for the new phenomena led at first to a confusion in which it appeared tha ...

Topological Quantum Computing
... Despite these difficulties, quantum error correction algorithms have been found. One such algorithm stores the quantum information redundantly, so that the information of one logical qubit is stored in three qubits. That is, the state that used to be described as, ψ = a | 0i + b | 1i is now describ ...
