Phys. Rev. A 54, 1715–1716 (1996)Relation between quantum computing and quantum controllabilityReceived 29 September 1995; published in the issue dated August 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. © 1996 The American Physical Society. © 1996 The American Physical Society URL:
