Percolation, renormalization, and quantum computing with non-deterministic gates
K. Kieling, T. Rudolph, J. Eisert
We apply a notion of static renormalization to the preparation of entangled states for quantum computing, exploiting ideas from percolation theory. Such a strategy yields a novel w…
A simple nearest-neighbor two-body Hamiltonian system for which the ground state is a universal resource for quantum computation
Stephen D. Bartlett, Terry Rudolph
We present a simple quantum many-body system - a two-dimensional lattice of qubits with a Hamiltonian composed of nearest-neighbor two-body interactions - such that the ground stat…
Reference frames, superselection rules, and quantum information
Stephen D. Bartlett, Terry Rudolph, Robert W. Spekkens
Recently, there has been much interest in a new kind of ``unspeakable'' quantum information that stands to regular quantum information in the same way that a direction in space or…
Ontological Models for Quantum Mechanics and the Kochen-Specker theorem
Terry Rudolph
Certain concrete "ontological models" for quantum mechanics (models in which measurement outcomes are deterministic and quantum states are equivalent to classical probability distr…
Degradation of a quantum directional reference frame as a random walk
Stephen D. Bartlett, Terry Rudolph, Barry C. Sanders +1
We investigate if the degradation of a quantum directional reference frame through repeated use can be modeled as a classical direction undergoing a random walk on a sphere. We dem…
How to observe a coherent superposition of an atom and a molecule
Mark R. Dowling, Stephen D. Bartlett, Terry Rudolph +1
We demonstrate that it is possible, in principle, to perform a Ramsey-type interference experiment to exhibit a coherent superposition of a single atom and a diatomic molecule. Thi…
