Physicists at the National Institute of Standards and Technology (NIST) have demonstrated the first "universal" programmable quantum information processor able to run any program allowed by quantum mechanics — the rules governing the submicroscopic world — using two quantum bits (qubits) of information. The processor could be a module in a future quantum computer, which [...]

Physicists at Harvard University have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in bizarre ways.
The work, published November 5 in the journal Nature, represents the first time scientists have detected single atoms in a crystalline structure [...]

Researchers at the Kavli Institute for Nanosciences at Delft University of Technology, have succeeded in getting hold of the environment of a quantum particle. This allows them to exercise greater control over a single electron, and brings the team of researchers, led by Vidi winner and FOM workgroup leader Lieven Vandersypen, a step closer still [...]

Quantum physics is both mysterious and difficult to grasp. Barry Sanders, director of the U of C’s Institute for Quantum Information Science, is hoping to change that.
Sanders, who is also the iCORE Chair of Quantum Information Science, has produced a four-minute animated movie with a team of animators and scientists. The film is intended for [...]

Quantum dots, tiny luminescent particles made of semiconductors, hold promise for detecting and treating cancer earlier. However, if doctors were to use them in humans, quantum dots could have limitations related to their size and possible toxicity.
Scientists at Emory University and the Georgia Institute of Technology have found a way around those limitations by exploiting [...]

The promise of quantum computing is that it will dramatically outshine traditional computers in tackling certain key problems: searching large databases, factoring large numbers, creating uncrackable codes and simulating the atomic structure of materials.
A quantum step in that direction, if you`ll pardon the pun, has been taken by Stanford researchers who announced their success in [...]

Quantum computers would likely outperform conventional computers in simulating chemical reactions involving more than four atoms, according to scientists at Harvard University, the Massachusetts Institute of Technology, and Haverford College. Such improved ability to model and predict complex chemical reactions could revolutionize drug design and materials science, among other fields.
Writing in the Proceedings of the [...]

Physicists in the USA and at the London Centre for Nanotechnology have found a way to extend the quantum lifetime of electrons by more than 5,000 per cent, as reported recently in Physical Review Letters. Electrons exhibit a property called ‘spin’ and work like tiny magnets which can point up, down or a quantum superposition [...]
