Scalable Ion Trap Quantum Computing without Moving Ions

L. Tian, R. Blatt, P. Zoller

A hybrid quantum computing scheme is studied where the hybrid qubit is made of an ion trap qubit serving as the information storage and a solid-state charge qubit serving as the qu…

Schroedinger Cat States of a Nanomechanical Resonator

L. Tian

We present a scheme of generating large-amplitude Schrödinger cat states and entanglement in a coupled system of nanomechanical resonator and single Cooper pair box (SCPB), without…

Full characterization of a three-photon GHZ state using quantum state tomography

Kevin J. Resch, Philip Walther, Anton Zeilinger

We have performed the first experimental tomographic reconstruction of a three-photon polarization state. Quantum state tomography is a powerful tool for fully describing the densi…

Coherent control of trapped ions using off-resonant lasers

J. J. Garcia-Ripoll, P. Zoller, J. I. Cirac

In this paper we develop a unified framework to study the coherent control of trapped ions subject to state-dependent forces. Taking different limits in our theory, we can reproduc…

Crucial Role of Quantum Entanglement in Bulk Properties of Solids

Caslav Brukner, Vlatko Vedral, Anton Zeilinger

We demonstrate that the magnetic susceptibility of strongly alternating antiferromagnetic spin-1/2 chains is an entanglement witness. Specifically, magnetic susceptibility of coppe…

Experimental Realization of a Photonic Bell-State Analyzer

Philip Walther, Anton Zeilinger

Efficient teleportation is a crucial step for quantum computation and quantum networking. In the case of qubits, four different entangled Bell states have to be distinguished. We h…
