Entanglement lies at the heart of quantum mechanics, and in recent years has been identified as an essential resource for quantum information processing and computation. The experimentally challenging production of highly entangled multi-particle states is therefore important for investigating both fundamental physics and practical applications. Here we report the creation of highly entangled states of neutral atoms trapped in the periodic potential of an optical lattice. Controlled collisions…

Multi-particle entanglement on an atom chip
The controlled generation of entanglement forms the basis for currently emerging ‘quantum technologies’, such as quantum simulation, computation, and metrology. In the field of quantum metrology,
Controlled exchange interaction between pairs of neutral atoms in an optical lattice
TLDR
This experiment uses an optical lattice of double-well potentials to isolate and manipulate arrays of paired 87Rb atoms, inducing controlled entangling interactions within each pair, and demonstrates the essential component of a neutral atom quantum SWAP gate (which interchanges the state of two qubits), which forms a set of universal gates for quantum computation.
Coherent manipulation of Bose–Einstein condensates with state-dependent microwave potentials on an atom chip
Entanglement-based technologies, such as quantum information processing, quantum simulations and quantum-enhanced metrology, have the potential to revolutionize our way of computing and measuring,
Interaction-induced decay of a heteronuclear two-atom system
TLDR
This experimental method allows us to single out a particular relaxation process and provides an extremely clean platform for collisional physics studies, and has implications for engineering of quantum states via controlled collisions and creation of two-qubit quantum gates.
The Advantages of Extra Entanglement
TLDR
Haas et al. (2) have demonstrated the creation of a robust entangled state of more than 40 ultracold atoms within a single operation that relies on a simultaneous, coherent interaction with the light field of a high-finesse optical cavity to reveal the presence of only a single atom with a different internal state.
Entanglement creation in cold molecular gases using strong laser pulses
While many-particle entanglement can be found in natural solids and strongly interacting atomic and molecular gases, generating highly entangled states between weakly interacting particles in a
Spatial entanglement of bosons in optical lattices.
TLDR
This work adopts recently developed approaches for the determination of rigorous lower entanglement bounds from readily accessible measurements and applies them in an experiment of ultracold interacting bosons in optical lattices of ~10(5) sites, constituting the first rigorous experimental large-scale entanglements quantification in a scalable quantum simulator.
A quantum gas microscope for detecting single atoms in a Hubbard-regime optical lattice
TLDR
A quantum gas ‘microscope’ that bridges the two approaches to creating highly controllable quantum information systems, realizing a system in which atoms of a macroscopic ensemble are detected individually and a complete set of degrees of freedom for each of them is determined through preparation and measurement.
Experiments on Multiphoton Entanglement
Entanglement lies at the heart of quantum mechanics and challenged the intuition of physicists ever since it was discovered. At the same time, it is a powerful tool that serves as a key resource for

Simulation of quantum dynamics with quantum optical systems
TLDR
The use of quantum optical systems to perform universal simulation of quantum dynamics and average Hamiltonian techniques are used to achieve evolutions in time according to a large class of Hamiltonians.
Persistent entanglement in arrays of interacting particles.
TLDR
These states can be regarded as an entanglement resource since one can generate a family of other multiparticle entangled states such as the generalized Greenberger-Horne-Zeilinger states of <N/2 qubits by simple measurements and classical communication.

TLDR
This report reports on the direct observation of an oscillating atomic current in a one-dimensional array of Josephson junctions realized with an atomic Bose-Einstein condensate, which may allow investigation of phenomena so far inaccessible to superconducting Josephsonjunctions and lays a bridge between the condensates dynamics and the physics of discrete nonlinear media.
