Signatures of incoherence in a quantum information processor
Michael K. Henry, Alexey V. Gorshkov, Yaakov S. Weinstein +8
Incoherent noise is manifest in measurements of expectation values when the underlying ensemble evolves under a classical distribution of unitary processes. While many incoherent p…
Selective coherence transfers in homonuclear dipolar coupled spin systems
Chandrasekhar Ramanathan, Suddhasattwa Sinha, Jonathan Baugh +2
Mapping the physical dipolar Hamiltonian of a solid-state network of nuclear spins onto a system of nearest-neighbor couplings would be extremely useful for a variety of quantum in…
The Real Density Matrix
Timothy F. Havel
We introduce a nonsymmetric real matrix which contains all the information that the usual Hermitian density matrix does, and which has exactly the same tensor product structure. Th…
Introduction to NMR Quantum Information Processing
R. Laflamme, E. Knill, D. G. Cory +11
After a general introduction to nuclear magnetic resonance (NMR), we give the basics of implementing quantum algorithms. We describe how qubits are realized and controlled with RF…
Interaction and Entanglement in the Multiparticle Spacetime Algebra
Timothy F. Havel, Chris J. L. Doran
The multiparticle spacetime algebra (MSTA) is an extension of Dirac theory to a multiparticle setting, which was first studied by Doran, Gull and Lasenby. The geometric interpretat…
Geometric Algebra in Quantum Information Processing
Timothy F. Havel, Chris J. L. Doran
This paper develops a geometric model for coupled two-state quantum systems (qubits), which is formulated using geometric (aka Clifford) algebra. It begins by showing how Euclidean…
