Benchmarking quantum control methods

Benchmarking quantum control methods on a 12-qubit system - This paper was reported in 2006 by Negrevergne and co-workers [6]. It describes a benchmark experiment in which a 12 qubit pseudo-cat state was successfully produced. It is the largest NMR quantum processing experiment to date. Besides, it reaches the minimum number of qubits required to leave the separability region established by Braunstein and co-workers [1] for room-temperature liquid-state NMR.
