Quantum computers offer another look at classic physics concepts

"Think what we can do if we teach a quantum computer to do statistical mechanics," posed Michael McGuigan, a computational scientist with the Computational Science Initiative at the U.S. Department of Energy's Brookhaven ...

Quantum Hall-based superconducting interference device

In a recent report published on Science Advances, Andrew Seredinski and co-workers presented a graphene-based Josephson junction with dedicated side gates fabricated from the same sheet of graphene as the junction itself. ...

Ions clear another hurdle toward scaled-up quantum computing

Scientists at the Joint Quantum Institute (JQI) have been steadily improving the performance of ion trap systems, a leading platform for future quantum computers. Now, a team of researchers led by JQI Fellows Norbert Linke ...

Preventing drugs from being transported from cells

An international research team has investigated the transport mechanism of a bacterial membrane protein using an artificially produced antibody fragment. The transport proteins, called ABC exporters, are present, for instance, ...

Remaining switched on to silicon-based electronics

The difficulty of further increasing the power conversion efficiency of silicon-based components in power electronics seems to indicate that we are reaching the limits of potential advances to this technology. However, a ...

Vulnerability of cloud service hardware uncovered

Field-programmable gate arrays (FPGAs) are kind of like a computer manufacturer's Lego bricks: electronic components that can be employed in a more flexible way than other computer chips. Even large data centers that are ...
