The circuit will improve the computational accuracy and efficiency of quantum computers operating at extremely low temperatures.
Quantum computers require an ambient temperature of approximately -273 degrees centigrade to function properly. The Technical Research Centre of Finland (VTT) is to build a control circuit for such a superconducting computer that will function at very low temperatures. Future quantum computers will be able to crack IT encryption codes and perform searches of enormous databases, which are currently impossible. The memory bits of a quantum computer may have several states simultaneously. This feature has enabled the few existing quantum computers, which although still primitive may yet achieve super efficiency in the future.
The high efficiency of a quantum computer facilitates computing far beyond the capacity of present-day equipment. For example, where current computers perform 1,000,000 searches in an unorganised database, quantum computers will perform approximately 1,000 searches, thus reducing the number by 1,000-fold. In the future the most extensive and complicated computing tasks can only be resolved with a quantum computer.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.
This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.
Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
