    We present preliminary STAR results on measurements of multi-strange particles Ξ\Xi, Ω\Omega and their anti-particles from Au+Au and Cu+Cu at sNN=62.4\sqrt{s_{NN}}=62.4 GeV collisions. In order to better understand the role of strangeness enhancement in nucleus-nucleus collisions and its scaling properties with system size, we compare the results from Au+Au and Cu+Cu reactions for different event centrality classes. Strangeness enhancement is discussed in the context of multi-strange to pion ratios. Finally, Ω/ϕ\Omega/\phi ratio is shown for different systems and energies for a systematic study

    Transmission Of Optical Coherent State Qubits

    We discuss the long distance transmission of qubits encoded in optical coherent states. Through absorption these qubits suffer from two main types of errors, the reduction of the amplitude of the coherent states and accidental application of the Pauli Z operator. We show how these errors can be fixed using techniques of teleportation and error correcting codes.Comment: Added two pages of explanation/background/review material to increase readability and clarity. Corrected minor typographical and linguistic error
