We have prepared the internal states of two trapped ions in both the Bell-like singlet and triplet entangled states. In contrast to all other experiments with entangled states of either massive particles or photons, we do this in a deterministic fashion, producing entangled states on demand without selection. The deterministic production of entangled states is a crucial prerequisite for large-scale quantum computation.

Generation of Maximally Entangled Bell State in a Coupled Quantum Dot

We show how the two interacting electrons in a field-driven coupled quantum dot can be used to prepare maximally entangled Bell states. The time durations of the oscillatory electric field for

Deterministic entanglement and tomography of ion–spin qubits

We have implemented a universal quantum logic gate between qubits stored in the spin state of a pair of trapped 40Ca ions. An initial product state was driven to a maximally entangled state

Quantum computing with trapped ions

Summary form only given. We have laser-cooled all modes of two ions and select modes of three ions to the ground state, thereby paving the way for subsequent quantum logic operations. We have also

Preparation of Entangled States of Three Particles by Adiabatic Passage

We propose a novel technique for the creation of entangled states of three particles, based upon an adiabatic passage induced by a suitably crafted time-dependent external field. We derive the

Quasideterministic generation of entangled atoms in a cavity.

A scheme to generate a maximally entangled state of two three-level atoms in a cavity by detecting the polarization of the photon leaking out of the cavity is presented.

Persistent entanglement in three-level atomic systems

We discuss the evolution towards persistent entangled state in an atom–photon system. A maximally entangled state can be stabilized at a local minimum of the system by draining some energy, thus

A Cavity-QED Scheme for Generating Long-Lived Maximally Entangled States

We propose a potentially practical scheme to generate two-atom maximally entangled states by the large-detuning interaction between two three-level Λ-type atoms and coherent optical fields.

Discussion on Maximally Entangled States of Two Coupled Two-Level Particles by Coherent State Approximation

We analyse the best condition for generating the maximally entangled states of the system containing two coupled two-level particles by the coherent approximation method beyond rotating wave

Generation of atomic entangled states using linear optics

In this paper, we propose a novel scheme that can generate two-atom maximally entangled states from pure product states and mixed states using linear optics. Because the scheme can generate pure
