Storing quantum information permanently

Quantum memory is one of the basic building blocks needed for realizing a quantum computer one day. Atac Imamoglu, a professor of quantum electronics, and Renato Renner, a professor of theoretical physics, examined the issue ...

Experts ponder era of big data

The era of big data has arrived. Last year, consumers and businesses around the world are estimated to have stored more than 13 exabytes of information on PCs, laptops and other devices - the equivalent of more than 52,000 ...

Don't stop anonymizing data

Canadian privacy experts have issued a new report today that strongly backs the practice of de-identification as a key element in the protection of personal information. The joint paper from Ontario's Information and Privacy ...

Sony shares tumble over latest cyber attack

Sony's share price fell more than three percent to a two-year low Monday after the latest online attack against the Japanese electronics and entertainment giant targeted its European subsidiary.

New kid on the plasmonic block

With its promise of superfast computers and ultrapowerful optical microscopes among the many possibilities, plasmonics has become one of the hottest fields in high-technology. However, to date plasmonic properties have been ...

Direct electronic readout of 'artificial atoms'

In addition to flows of electrons, researchers are seeking options for the spin of electrons to be used in future information processing. In combination with these characteristics, a considerably larger volume of information ...

Smallest magnetic field sensor in the world developed

Further development of modern information technology requires computer capacities of increased efficiency at reasonable costs. In the past, integration density of the relevant electronic components was increased constantly. ...

Quantum computing with braids in flatland

Exotic anyon quasiparticles trapped in two dimensional sheets can entangle into braided structures that are less susceptible to the disturbances that disrupt individual quasiparticles in quantum computations.
