Relation between quantum computing and quantum controllability
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 quantum computing and quantum control is deeper in that tools of coherent control of quantum dynamics may be used to arrive at specific designs for quantum computing devices. \textcopyright{} 1996 The American Physical Society.
