Towards Robust Quantum Computation
Debbie W. Leung
Quantum computation is a subject of much theoretical promise, but has not been realized in large scale, despite the discovery of fault-tolerant procedures to overcome decoherence.…
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…
Hiding bits in Bell states
Barbara M. Terhal, David P. DiVincenzo, Debbie W. Leung
We present a scheme for hiding bits in Bell states that is secure even when the sharers Alice and Bob are allowed to carry out local quantum operations and classical communication.…
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…
Methodology for quantum logic gate constructions
Xinlan Zhou, Debbie W. Leung, Isaac L. Chuang
We present a general method to construct fault-tolerant quantum logic gates with a simple primitive, which is an analog of quantum teleportation. The technique extends previous res…
