Geometric phase gate on an optical transition for ion trap quantum computation
K. Kim, C. F. Roos, L. Aolita +3
We propose a geometric phase gate of two ion qubits that are encoded in two levels linked by an optical dipole-forbidden transition. Compared to hyperfine geometric phase gates med…
Ion trap quantum gates with amplitude-modulated laser beams
Christian F. Roos
In ion traps, entangling gate operations can be realized by a bichromatic pair of laser beams that collectively interact with the ions. In this paper, a new method of modelling the…
Experimental realization of a quantum game on a one-way quantum computer
Robert Prevedel, Andre Stefanov, Philip Walther +1
We report the first demonstration of a quantum game on an all-optical one-way quantum computer. Following a recent theoretical proposal we implement a quantum version of Prisoner's…
Completeness of the classical 2D Ising model and universal quantum computation
M. Van den Nest, W. Dür, H. J. Briegel
We prove that the 2D Ising model is complete in the sense that the partition function of any classical q-state spin model (on an arbitrary graph) can be expressed as a special inst…
How to create and detect N-dimensional entangled photons with an active phase hologram
Martin Stuetz, Simon Groeblacher, Thomas Jennewein +1
The experimental realization of multidimensional quantum states may lead to unexplored and interesting physics, as well as advanced quantum communication protocols. The orbital ang…
Toolbox for entanglement detection and fidelity estimation
Otfried Gühne, Chao-Yang Lu, Wei-Bo Gao +1
The determination of the state fidelity and the detection of entanglement are fundamental problems in quantum information experiments. We investigate how these goals can be achieve…
