Chalmers researchers in Sweden, in an EU project involving colleagues from France, Holland, Germany, Italy and Finland, have shown that outdata from superconductor quantum computers can be read directly, even though the signal consists only of the presence or absence of two electrons, a so-called Cooper pair.
How far away are we from a functional quantum computer? Research results on quantum computers are beginning to appear. Göran Johansson at the Department of Microelectronics and Nanoscience reports that the Chalmers research team he is a member of has been able to produce readouts of superconductor quantum computers. The key to success lies in being able to meter tiny charges before they move on.
Different research teams are studying different problems involving quantum computers. Research is pursuing many paths at the same time. “But even very simple quantum computers are still at least ten years down the road,” says Göran.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
