Quantum computation via measurements on the low-temperature state of a many-body system

David Jennings, Andrzej Dragan, Sean D. Barrett +2

We consider measurement-based quantum computation using the state of a spin-lattice system in equilibrium with a thermal bath and free to evolve under its own Hamiltonian. Any sing…

Phase transitions and localizable entanglement in cluster-state spin chains with Ising couplings and local fields

Stein Olav Skrøvseth, Stephen D. Bartlett

We consider a one-dimensional spin chain for which the ground state is the cluster state, capable of functioning as a quantum computational wire when subjected to local adaptive me…

Characterizing measurement-based quantum gates in quantum many-body systems using correlation functions

Thomas Chung, Stephen D. Bartlett, Andrew C. Doherty

In measurement-based quantum computation (MBQC), local adaptive measurements are performed on the quantum state of a lattice of qubits. Quantum gates are associated with a particul…

Frank-Condon principle and adjustment of optical waveguides with nonhomogeneous refractive indices

Vladimir I. Man'ko, Leonid D. Mikheev, Alexandr Sergeevich

The adjustment of two different selfocs is considered using both exact formulas for the mode-connection coefficients expressed in terms of Hermite polynomials of several variables…

Quantum communication using a bounded-size quantum reference frame

Stephen D. Bartlett, Terry Rudolph, Robert W. Spekkens +1

Typical quantum communication schemes are such that to achieve perfect decoding the receiver must share a reference frame with the sender. Indeed, if the receiver only possesses a…

Alternative fidelity measure for quantum states

Paulo E. M. F. Mendonca, Reginaldo d. J. Napolitano, Marcelo A. Marchiolli +2

We propose an alternative fidelity measure (namely, a measure of the degree of similarity) between quantum states and benchmark it against a number of properties of the standard Uh…
