New NbRe Alloy Shows Promise for Quantum Superconductivity

2/21/2026

Summary

Story summary

Researchers led by Professor Jacob Linder of the Norwegian University of Science and Technology (NTNU) report potential evidence of triplet superconductivity in the niobium–rhenium (NbRe) alloy, which could enable zero-resistance transport and improve stability and energy efficiency of quantum computers.
NbRe operates around 7 Kelvin, higher than many candidates.
If independently verified, NbRe could aid next-generation quantum devices and spintronics.
The findings were published in Physical Review Letters.
