Room-temperature superconductor: Is Holy Grail in grasp?
Nature magazine retracted a 2020 article by Ranga P. Dias of the University of Rochester and others on developing a superconductor that worked at about 15°C, as the results couldn’t be replicated.
Dias and colleagues also claim a new superconducter of lutetium, hydrogen and nitrogen at room temperature, but doubts persist. Computers process information with bits—ones and zeroes.
But two bits can only represent one of four possible states at one time. Superconductors are the building blocks of quantum computers that use quantum bits, or qubits, to process ones and zeroes at the same time -- it’s like running four computers in one.
The physical qubits are typically super-cooled to avoid errors. This research could get them to work at room temperature and ambient pressure without the need for elaborate cooling systems.
