NP-hardness of decoding quantum error correction codes
NP-hardness quantum error correction codes
2010/10/18
Though the theory of quantum error correction is intimately related to the classical coding theory,in particular, one can construct quantum error correction codes (QECCs) from classical codes with the...
Silicon Photo-Multiplier radiation hardness tests with a beam controlled neutron source
Silicon Photo-Multiplier beam controlled neutron source
2010/3/16
We report radiation hardness tests performed at the Frascati Neutron Generator on silicon Photo-Multipliers, semiconductor photon detectors built from a square matrix of avalanche photo-diodes on a si...
Radiation hardness of CMS pixel barrel modules
LHC super LHC CMS tracking pixel silicon radiation hardness
2010/3/15
Pixel detectors are used in the innermost part of the multi purpose experiments at LHC and are therefore exposed to the highest fluences of ionising radiation, which in this part of the detectors cons...
Effects of Plasma Immersion Ion Implantation (PIII) of Nitrogen on Hardness, Composition and Corrosion Resistance of Ti-6Al-4V Alloy
Corrosion Hardness Plasma immersion ion implantation Ti-6Al-4V X-ray diffraction
2010/9/29
Ti-6Al-4V samples have been treated by PIII processing at different temperatures (400-800 ° C), treatment time (30-150 min) and plasma potential (100 and 420 V). Hardness measurements results showed a...
Study of Vickers´ Micro Hardness on InBi0.85Sb0.15 Single Crystals
Vickers' micro hardness Cold-worked crystals Annealed crystals Zone-melting method
2010/4/9
InBi0.85Sb0.15 single crystals have been grown by zone-melting method. The growth velocity was 0.8 cm/h and the freezing interface temperature was 35 °C/cm. A Vickers' projection microscope was used f...
