4 Qubit Search Implementation
Technology Review: Sturdy Quantum Computing Demoed: "Researchers at the University of Toronto have built a prototype quantum computer that can execute a quantum search algorithm despite environmental noise. The computer uses protected logical qubits that are made from multiple physical qubits. The prototype has just four qubits, but the method has the potential to someday be used in practical quantum computers, which require thousands or millions of qubits. [...] The work appeared in the November 21, 2003 issue of Physical Review Letters."
