In a world-first, a team of researchers from TU Delft demonstrated a one-way superconductor with zero resistance that blocks any current coming in the opposite direction. Find out more at 💻 Engineering
and make a very, very thin sandwich — just a few atomic layers thick — which was needed for making the Josephson diode, and was not possible with normal 3D materials,""Many technologies are based on old versions of JJ superconductors," Ali continued."For example, MRI technology. Also, quantum computing today is based on Josephson Junctions.
However, one obstacle the researchers need to overcome is the question of usability at room temperature. The tests so far have been run atbelow 77 Kelvin . If the TU Delft team can figure out how to run the JJ superconductor at more normal temperatures — something Ali says is possible with "known High Tc Superconductors" — then they will be much closer to the next step, which is to investigate whether it can be scaled for mass production.
The TU Delft researchers believe their superconductor would be best used in centralized server farms and supercomputers. They would help benefit the most considerable amount of people at the lowest cost. "The existing infrastructure could be adapted without too much cost to work with Josephson diode-based electronics," Ali said."There is a very real chance, if the challenges discussed in the other question are overcome, that this will revolutionize centralized and supercomputing!"Stay ahead with the latest science, technology and innovation news, for free:
