Researchers from Cornell University have identified a new state of matter in candidate topological superconductors, a discovery that may have far-reaching implications for both condensed matter physics and the fields of quantum computing and spintronics. Researchers at the Macroscopic Quantum Mat
Scientists at Cornell discovered a new quantum matter state in Uranium Ditelluride, which could revolutionize quantum computing and spintronics by forming the materials platform for ultra-stable quantum computers and revealing new avenues for identifying such states in various materials.
However, even after a decade of intense investigation into topological superconductivity, no bulk materials have been definitively recognized as spin-triplet, odd-parity superconductors, with the exception of superfluid 3He, which was also discovered at Cornell. Recently, the exotic new material Uranium Ditelluride has emerged as a highly promising candidate for this classification. However, its superconductive order parameter remains elusive, said Gu.
In simple terms, a PDW is like a stationary dance of the paired electrons found in a superconductor, but the pairs form periodic crystalline patterns in space. Cooper-pair density waves are a form of electronic quantum matter in which pairs of electrons freeze into a superconductive PDW state, instead of forming a conventional “superconductive” fluid where all are in the same freely moving state.

Quantum computer unveils atomic dynamics of light-sensitive moleculesResearchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.
