Majorana 1: Towards Topological Qubit Quantum Computing

On February 19, 2025 Microsoft unveiled its Majorana 1 topological qubit quantum processor. The company is currently developing a scalable quantum computing architecture built around a single-qubit device called a tetron. Built with a novel class of materials dubbed a topoconductor, the quantum chip utilizes a new state (or phase) of matter that is not based on solid, liquid or gas. In theory, topological qubits are more powerful than logical qubits. Logical qubits often contain 1000+ physical qubits, to get to error corrected quantum computing protected from environmental decoherence.
