A group of researchers from the National Institute of Standards and Technology (NIST) has discovered that a particular superconducting material, the compound uranium ditelluride, or UTe2, could prove very useful in quantum computers to support the so-called quantum coherence.
The latter fails when, precisely in quantum computers, when the qubits cannot function for the time necessary to terminate the calculation. Quantum coherence, in quantum computers, is difficult to maintain due to various environmental disturbances, even the weakest.
According to researchers at the US institute, this new superconducting material could finally make it possible to build effective quantum logic circuits thanks to its resistance to magnetic fields, a rare thing among superconducting materials.
“This is potentially the silicon of the quantum information era,” reports Nick Butch, one of the designers on the research team who made the discovery.
The tiny qubits built with this material could be easily shielded and protected from the surrounding environment, especially from the rest of the computer components.
The results of the study were published in Science.
