Abstract
Any realistic approach to quantum computing must be capable of implementing a sufficiently large number of qubits to perform useful computations. It has been estimated that 104 qubits may be required to implement Shor’s factoring algorithm for integers of useful size, and that this number may grow to 10 6 qubits when the redundant bits required for quantum error correction are included. Many of the quantum computer implementations currently being investigated, such as ion traps or NMR techniques, provide a reasonably straight-forward method for implementing a few qubits but are subject to fundamental limitations on the number of qubits that can be implemented [1], [2].
