Hamiltonians for Quantum Computing
Vladimir Privman, Dima Mozyrsky, Steven P. Hotaling
We argue that the analog nature of quantum computing makes the usual design approach of constructing complicated logical operations from many simple gates inappropriate. Instead, w…

Design of gates for quantum computation: the three-spin XOR gate in terms of two-spin interactions
Dima Mozyrsky, Vladimir Privman, Steven P. Hotaling
We propose to design multispin quantum gates in which the input and output two-state systems (spins) are not necessarily identical. We describe the motivations for such studies and…

Extended Quantum XOR Gate in Terms of Two-Spin Interactions
Dima Mozyrsky, Vladimir Privman, Steven P. Hotaling
Considerations of feasibility of quantum computing lead to the study of multispin quantum gates in which the input and output two-state systems (spins) are not identical. We provid…
