Viswanath Ramakrishna, HERSCHEL A. RABITZ • Physical Review A
(1996)
It is demonstrated that the universality of any quantum computing element can be understood and verified via a precise mathematical criterion which tests for the controllability of an associated quantum control system. This relation between...
