Microsoft researchers say they created a chip that leverages a new state of matter that could underpin quantum computers more powerful than the world has ever seen. The chip employs a so-called “topological superconductor”—a material that isn’t a solid,

Microsoft has announced Majorana 1 as the first quantum-computing chip powered by what it terms as a new topological core architecture. The company said Wednesday it expects the chip will make quantum computers capable of solving meaningful,
