A Step Towards Quantum Electronics
December 18, 2015 | Université de GenèveEstimated reading time: 2 minutes
In general, it is difficult to produce a clean junction between quantum materials. Thanks to the collaboration between the teams in Geneva and Zurich, an important step has now been taken towards developing efficient junctions. For their ultracold atoms, the researchers produced junctions with a transparency close to 100 %. This advance is a crucial step towards understanding quantum transport in ultracold atoms and will enable fundamental studies of superconductors and other quantum materials. But interconnecting quantum materials such as superconductors might bring also new possibilities for more efficient information processing, beyond what is possible with techniques currently available for connecting, in computers and electronic devices, active elements such as transistors to form electronic circuits.
Now that junctions between quantum materials with strong interactions can be produced, scientists might eventually create novel materials that can be used in everyday applications. The unconventional approach developed in Geneva and Zurich therefore establishes the first basis for new technologies and opens up a new research direction that might lead to creating ultrafast and robust electronic networks — a dream that many physicists share.

New RF Materials Offer Options for RF Designers
04/29/2025 | Andy Shaughnessy, Design007 MagazineThe RF materials arena has changed quite a bit in the past decade. The newest thermoset laminates boast performance numbers that are almost competitive with PTFE, but without the manufacturability challenges. At IPC APEX EXPO this year, I spoke with Brent Mayfield, business development manager at AGC Multi Material America. Brent walked through some recent innovations in RF materials, advances in resin systems, and the many design trade-offs for RF engineers to consider for each material set.
Discovery Opens Doors for Cheaper and Quicker Battery Manufacturing
04/23/2025 | PNNLThe discovery centers on sublimation, a commonly known process whereby under the right conditions, a solid turns directly into a vapor. Sublimation is what creates the tail of a comet as it flies by the sun. As the comet’s icy shell heats up, the ice instantly becomes vapor, instead of first melting into liquid water.
