Researchers report superconductivity in boron-doped diamond at ultracold temperatures
A team just made a big leap toward quantum chips made from diamonds.
By swapping some carbon atoms for boron, they found the diamond could carry electricity with zero resistance at super cold temperatures—pretty wild for a gemstone!
This breakthrough, published in PNAS on May 11, brings us closer to using diamonds in next-generation tech.
Quantum puddles appear at minus 269.85°C
The researchers used a special method to create ultra-thin diamond films packed with boron.
This led to the discovery of "quantum puddles," tiny spots where superconductivity kicks in at minus 269.85 Celsius and spreads as things get colder.
Experiments with magnets showed unusual patterns, hinting that diamond chips could mix regular and quantum tech on one platform, making future devices simpler and more powerful.
