Journal ArticleDOI
Quantum dynamics of single trapped ions
TL;DR: Theoretical and experimental work on radio-frequency (Paul) traps is reviewed in this paper, with a focus on ions trapped in radiofrequency traps, which are ideal for quantum-optical and quantum-dynamical studies under well controlled conditions.

Experimental issues in coherent quantum-state manipulation of trapped atomic ions
David J. Wineland,Christopher Monroe,Wayne M. Itano,Dietrich Leibfried,B. E. King,D. M. Meekhof +5 more
TL;DR: In this article, the generation of entangled states of trapped atomic ions is described in terms of quantum logic operations since the conditional dynamics implicit in quantum logic is central to the creation of entanglement.
Journal ArticleDOI
Deterministic quantum teleportation of atomic qubits.
Murray D. Barrett,Murray D. Barrett,John Chiaverini,Tobias Schaetz,Joseph W. Britton,Wayne M. Itano,John D. Jost,Emanuel Knill,Christopher Langer,Dietrich Leibfried,Roee Ozeri,David J. Wineland +11 more
TL;DR: Un unconditional teleportation of massive particle qubits using atomic (9Be+) ions confined in a segmented ion trap is reported, which achieves an average fidelity of 78 per cent, which exceeds the fidelity of any protocol that does not use entanglement.
Journal ArticleDOI
Experimental demonstration of a robust, high-fidelity geometric two ion-qubit phase gate
Dietrich Leibfried,Brian DeMarco,V. Meyer,D. M. Lucas,D. M. Lucas,Murray D. Barrett,Joseph W. Britton,Wayne M. Itano,Branislav M. Jelenkovic,C. Langer,Till Rosenband,David J. Wineland +11 more
TL;DR: A universal geometric π-phase gate between two beryllium ion-qubits is demonstrated, based on coherent displacements induced by an optical dipole force, which makes it attractive for a multiplexed trap architecture that would enable scaling to large numbers of ions.
Journal ArticleDOI
Creation of a six-atom ‘Schrödinger cat’ state
Dietrich Leibfried,Emanuel Knill,S. Seidelin,Joseph W. Britton,R. B. Blakestad,John Chiaverini,John Chiaverini,David Hume,Wayne M. Itano,John D. Jost,Christopher Langer,Roee Ozeri,R. Reichle,David J. Wineland +13 more
TL;DR: The creation of cat states of up to six atomic qubits is reported, which represents the current state-of-the-art for large entangled states in any qubit system.
