Bell's theorem states that certain statistical correlations predicted by quantum physics for measurements on two-particle systems cannot be understood within a realistic picture based on local properties of each individual particle—even if the two particles are separated by large distances. Einstein, Podolsky and Rosen first recognized the fundamental significance of these quantum correlations (termed ‘entanglement’ by Schrödinger) and the two-particle quantum predictions have found ever… 
Compact Greenberger—Horne—Zeilinger state generation via frequency combs and graph theory
Quantum entanglement is one of the most mindboggling phenomena predicted by quantum physics. It says that two particles can influence each other, even though they are separated over large distances.
Preparation and measurement of three-qubit entanglement in a superconducting circuit
Deterministic production of three-qubit Greenberger–Horne–Zeilinger (GHZ) states with fidelity of 88 per cent is demonstrated, demonstrating the first step of basic quantum error correction, namely the encoding of a logical qubit into a manifold of GHZ-like states using a repetition code.
Experimental demonstration of five-photon entanglement and open-destination teleportation
A proof-of-principle demonstration of five-photon entanglement and open-destination teleportation and can be used for investigations of measurement-based quantum computation and multi-party quantum communication.
Experimental Greenberger–Horne–Zeilinger entanglement beyond qubits
A three-dimensionally entangled Greenberger–Horne–Zeilinger state, where all three photons reside in a qutrit space, is generated by developing a new multi-port in combination with a novel four-photon source entangled in orbital angular momentum.
In search of superluminal quantum communications: recent experiments and possible improvements
As shown in the famous EPR paper (Einstein, Podolsky e Rosen, 1935), Quantum Mechanics is non-local. The Bell theorem and the experiments by Aspect and many others, ruled out the possibility of
Experimental test of the irreducible four-qubit Greenberger-Horne-Zeilinger paradox
Bell's theorem shows a profound contradiction between local realism and quantum mechanics on the level of statistical predictions. It does not involve directly Einstein-Podolsky-Rosen (EPR)
Experimental Greenberger-Horne-Zeilinger-Type Six-Photon Quantum Nonlocality.
This experiment experimentally demonstrates the six-photon quantum nonlocality in an all-versus-nothing manner based on a high-fidelity Greenberger-Horne-Zeilinger state for device-independent quantum information protocols.
Experimental test of non-classicality of quantum mechanics using an individual atomic solid-state quantum system
Quantum mechanics provides a statistical description about nature, and thus would be incomplete if its statistical predictions could not be accounted for some realistic models with hidden variables.
Multi-Photon Entanglement and Quantum Non-Locality
We review recent experiments concerning multi-photon Greenberger-Horne-Zeilinger (GHZ) entanglement. We have experimentally demonstrated GHZ entanglement of up to four photons by making use of pulsed
Investigations of fundamental phenomena in quantum mechanics with neutrons
Neutron interferometer and polarimeter are used for the experimental investigations of quantum mechanical phenomena. Interferometry exhibits clear evidence of quantum-contextuality and polarimetry


Observation of three-photon Greenberger-Horne-Zeilinger entanglement
We present the experimental observation of polarization entanglement for three spatially separated photons. Such states of more than two entangled particles, known as Greenberger-Horne-Zeilinger
Bell’s theorem without inequalities
It is demonstrated that the premisses of the Einstein–Podolsky–Rosen paper are inconsistent when applied to quantum systems consisting of at least three particles. The demonstration reveals that the
Entangling Photons Radiated by Independent Pulsed Sources a
By pumping two or more downconversion crystals with a pulsed laser, it is experimentally feasible to obtain with nonnegligible probability one photon pair from each crystal within a pulse, and it is observed that the signal photons emitted together with the idlers are projected onto the desired entangled state.
Proposal for a loophole-free Bell inequality experiment.
A two-crystal down-conversion source, relying on type-II collinear phase matching, which should permit a violation of Bell's inequalities without the need for supplementary assumptions is proposed.
NMR Greenberger–Horne–Zeilinger states
The Greenberger–Horne–Zeilinger (GHZ) state is created using Nuclear Magnetic Resonance (NMR) and the space of entangled quantum states explored systematically is extended to three quantum bits, an essential step for quantum computation.
Critical visibility for N -particle Greenberger-Horne-Zeilinger correlations to violate local realism
A sequence of Bell inequalities for N-particle systems, which involve three settings of each of the local measuring apparatuses, is derived. For Greenberger-Horne-Zeilinger states, quantum mechanics
Experimental quantum teleportation
It is shown that during teleportation, one of a pair of entangled photons are subjected to a measurement such that the second photon of the entangled pair acquires the polarization of the initial photon.
What's Wrong with these Elements of Reality?
The subject of Einstein-PodolskyRosen correlations—those strong quantum correlations that seem to imply "spooky actions at a distance"—has just been given a new and beautiful twist. Daniel
