Secure quantum channels with correlated twin laser beams
This work is the development and analysis of the recently proposed quantum
cryptographic protocol, based on the use of the two-mode coherently correlated
states. The protocol is supplied with the cryptographic control procedures. The
quantum noise influence on the channel error properties is examined. State
detection features are proposed
Four-gap glass RPC as a candidate to a large area thin time-of-flight detector
A four-gap glass RPC with 0.3mm gap size was tested with hadron beam as a
time-of-flight detector having a time resolution of ~ 100ps. A thickness of the
detector together with front-end electronics is ~ 12mm. Results on time
resolution dependently on a pad size are presented. This paper contains first
result on the timing RPC (with ~ 100ps resolution) having a strip read-out.
Study has been done within the HARP experiment (CERN-PS214) R&D work. A obtaned
data can be useful if a design of a large area thin timing detector has to be
done.Comment: 18 pages, 13 figure
