We report a free space based experimental demonstration of a two way Quantum Key Distribution protocol withweak+vacuum decoy state. By utilizing a different key rate formula a better maximum secure distance closer to the theoretical infinite was achieved.Proceedings of The 3rd International Conference on Cryptology & Computer Security 2012 (Cry

An apparatus for flipping the polarization state of an optical pulse between a transmitter and a receiver in a quantum key distribution system comprising: a passive non flipping component that preserves the polarization state of said optical pulse; a passive flipping component that rotates the polarization state of said optical pulse orthogonally;

Cellulase enzymes is expensive in the market due to the high cost of pure cellulose was used as substrate fermentation in its production. It is an important enzyme in many industries such as food, textile, fuel and pharmaceutical. In this study, oil palm empty fruit bunch (OPEFB) was used as substrate for the production of cellulose by strain RUT C

In Islam, marriage is expected to last until one of the spouses dies. However, if the spouses cannot live together in peace and harmony any more in the marital relationship, then its continuance is no longer considered desirable. Divorce is permitted as a matter of necessity for the avoidance of greater evil, which may result from the continuance o

We report an implementation of a two-way, four-state quantum key distribution (QKD) protocol (namely, the LM05 protocol) over a free space medium. A stable quantum bit error rate of 3.34% and maximum tolerable channel loss for secure key generation of 5.68 dB in the absence of a photon number splitting attack were recorded. The result strongly indi

The erroneous signal detection characterizes the quality of alignment and stability of a Quantum Key Distribution (QKD) system. Its effect against the improvement to the maximum secure distance achievable with weak+vacuum decoy state and a two way Quantum Key Distribution protocol, namely the LM05 protocol is investigated. The result from our numer

This article focuses on the issues of conversion of one of the party to a non-Muslim marriage to Islam. In Malaysia, there are some legal problems that need to be addressed particularly concerning the rights of a wife to the ancillary claims after the dissolution of the marriage such as maintenance, matrimonial property and custody. These issues ha

The effect of plant oils (olive, palm, corn, sunflower and soya bean) addition at different concentrations (0.5%. 1.0%, 2.0% and 4.0%) producing mycelium biomass (MBS) and exopolysaccharides (EPS) in submerged fermentation using a local strain Schizophyllum commune was determined. Additional of all type of plant oils exhibit higher yield of MBS and

The fact that the 2D shallow-water model has been used for decades is such a long time that a complete reference on how to derive it from the primitive equations either has likely to become a very rare article or written in a way that is very complicated for the newcomers. Certain physical assumptions and mathematical theorem should be acquired in
