Maximally entangled states of four nonbinary particles

Abstract

Four different aggregation-precipitation (AP) stages of the divalent europium (Eu2+) ions have been fixed in KBr single crystals by means of heat treating processes. To examine the dissolution of the ions configuration (AP stages), the samples are continuously heated for activating the ions diffusion. This process is monitored in situ by the pulsed photoacoustic (PA) technique. To follow the ions configuration dissolution, the PA signals at each temperature are successively acquired. AP stage of ions changes are recovered by a numerical procedure based on the correlation coefficients. This procedure applied to digitally recorded PA signals allowed the construction of an AP profile Ns(Tt), where is easier to analyze the ions behaviour into the crystal host. The results agree with those obtained by the optical absorption analysis, under similar conditions. The PA signal is generated as a consequence of the non-radiative processes that have taken place after the excitation of the Europium ion. This excitation, which corresponds to an electronic transition to the low energy absorption band T2g of the Eu2+ ions, is achieved by means of a laser pulse at 355 nm focused on the sample.

Lawrence, J.",,"2015",,"Systems of four nonbinary particles, with each particle having d?3 internal states, exhibit maximally entangled states that are inaccessible to four qubits. This breaks the pattern of two- and three-particle systems, in which the existing graph states are equally accessible to binary and nonbinary systems alike. We compare the entanglement properties of these special states (called P states) with those of the more familiar Greenberger-Horne-Zeilinger (GHZ) and cluster states accessible to qubits. The comparison includes familiar entanglement measures, the "steering" of states by projective measurements, and the probability that two such measurements, chosen at random, leave the remaining particles in a Bell state. These comparisons demonstrate not only that P-state entanglement is stronger than the other types but also that it is maximal in a well-defined sense. We prove that GHZ, cluster, and P states represent all possible entanglement classes of four-particle graph states with prime d?3. " 2015 American Physical Society.
