Multi-strange particle production in relativistic heavy ion collisions at GeV
We present preliminary STAR results on measurements of multi-strange
particles , and their anti-particles from Au+Au and Cu+Cu at
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,
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
