Realization of quantum process tomography in NMR
Andrew M. Childs, Isaac L. Chuang, Debbie W. Leung
Quantum process tomography is a procedure by which the unknown dynamical evolution of an open quantum system can be fully experimentally characterized. We demonstrate explicitly ho…

Quantum Vernam Cipher
D. W. Leung
We discuss aspects of secure quantum communication by proposing and analyzing a quantum analog of the Vernam cipher (one-time-pad). The quantum Vernam cipher uses entanglement as t…

Universal simulation of Markovian quantum dynamics
Dave Bacon, Andrew M. Childs, Isaac L. Chuang +3
Although the conditions for performing arbitrary unitary operations to simulate the dynamics of a closed quantum system are well understood, the same is not true of the more genera…
