Scientists just predicted a new material that is both a perfect conductor and a quantum "wonder," which is basically the holy grail for super-fast computers.

The Takeaway
Superconductivity lets electricity flow forever, while "topology" protects electronic information from being destroyed. Finding one material that naturally does both could lead to quantum computers that actually work without the constant errors that plague current designs.
From the abstract
Two-dimensional (2D) materials that host both Dirac points and van Hove singularities (VHSs) provide a fertile platform for exploring exotic quantum states, including high-temperature ferromagnetism and topological superconductivity. However, material candidates simultaneously exhibiting non-trivial electronic topology and intrinsic superconductivity remain rare. Here, we predict two rectangular 2D monolayers, $\text{ScSiCl}$ and $\text{ScSiBr}$, with exceptional stabilities by first-principles
