Adders and multipliers are two main units of the computer arithmetic processors and play an important role in reversible computations. The binary multiplier consists of two main parts, the partial products generation circuit (PPGC) and the reversible parallel adders (RPA). This paper introduces a novel reversible 4×4 multiplier circuit that is based on an advanced PPGC with Peres gates only. Ag...

 Background: This research studied the feasibility of a simple method for extracting gold from central processing units (CPUs) of computer circuit boards without solvent. Methods: Ceramic and composite CPUs of computer circuit boards were used. Gold was extracted using a hydrometallurgical method in six stages: grinding of CPUs, leaching in nitric acid, leaching in aqua regia, remov...

When a universal quantum computer is used by the public, it assumed that will be in form of cloud server exists few bases due to its cost. In this server, privacy crucial issue, and blind computation protocol necessary so each user can use without details calculations being revealed. It also important able verify performing as instructed user, since cannot verified classical computation. paper,...
