EBL signature on VHE gamma photons
"... Very high energy (VHE, E> 30 GeV) gammarays are absorbed via interaction with lowenergy photons from the extragalactic background light (EBL) if the involved photon energies are above the threshold for electronpositron pair creation. The VHE gammaray absorption, which is energy dependent and ..."

The project innovates in several areas of PET systems, from optical coupling to singlephoton sensor architectures, from intelligent ring networks to reconstruction
Results of Gamma Photon and Neutron Irradiations of Hamamatsu R560003/NG
"... Gamma photon and neutron irradiation tests were carried out to study the applicability of R560003/NG miniature photomultiplier tubes (PMTs) from Hamamatsu in the forward calorimeters (HF) of the hadron calorimeter (HCAL) of the Compact Muon Solenoid (CMS). Results of optical and dark current measur ..."

The Determination of Oxygen and Carbon in Indium Phosphide by Highenergy Gammaphoton Activation
"... Highenergy gammaphoton activation has been used for the determination of carbon and oxygen in singlecrystal indium phosphide at concentrations in the range 0.01 to 01 p.p.m. m/m and less than 0.05 p.p.m. m/m, respectively. REQUIREMENTS for the determination of light elements at very low levels ..."

Simulating Physics with Computers

"... A digital computer is generally believed to be an efficient universal computing device; that is, it is believed able to simulate any physical computing device with an increase in computation time of at most a polynomial factor. This may not be true when quantum mechanics is taken into consideration. ..."

A digital computer is generally believed to be an efficient universal computing device; that is, it is believed able to simulate any physical computing device with an increase in computation time of at most a polynomial factor. This may not be true when quantum mechanics is taken into consideration. This paper considers factoring integers and finding discrete logarithms, two problems which are generally thought to be hard on a classical computer and have been used as the basis of several proposed cryptosystems. Efficient randomized algorithms are given for these two problems on a hypothetical quantum computer. These algorithms take a number of steps polynomial in the input size, e.g., the number of digits of the integer to be factored. AMS subject classifications: 82P10, 11Y05, 68Q10. 1 Introduction One of the first results in the mathematics of computation, which underlies the subsequent development of much of theoretical computer science, was the distinction between computable and ...
Teleporting an Unknown Quantum State via Dual Classical and EPR Channels
, 1993
"... An unknown quantum state jOEi can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical EPR correlations. To do so the sender, "Alice," and the receiver, "Bob," must prearrange the sharing of an EPRcorrelated pair of particles. ..."

An unknown quantum state jOEi can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical EPR correlations. To do so the sender, "Alice," and the receiver, "Bob," must prearrange the sharing of an EPRcorrelated pair of particles. Alice makes a joint measurement on her EPR particle and the unknown quantum system, and sends Bob the classical result of this measurement. Knowing this, Bob can convert the state of his EPR particle into an exact replica of the unknown state jOEi which Alice destroyed. Expanded version of manuscript submitted to Phys. Rev. Lett. December 1992 PACS numbers: 03.65.Bz, 42.50.Dv, 89.70.+c (a) Permanent address. The existence of long range correlations between EinsteinPodolskyRosen (EPR) [1] pairs of particles raises the question of their use for information transfer. Einstein himself used the word "telepathically" in this context [2]. It is known that instantaneous information transfer is definitely impossib...
