Microsoft has made major advances in quantum computing by developing stable, controllable qubits (quantum particles) based on a new topological architecture. These qubits, called Majoranas, exhibit inherent robustness against environmental noise and promise higher speeds, smaller size and easier control compared to conventional qubit designs.

Developing these qubits was a grand challenge that required breakthroughs in engineering and materials science, the science that studies the properties of materials. Microsoft developed a hybrid material stack with indium arsenide, a semiconductor known for its unique properties, combined with superconductivity at extremely low temperatures. This combination creates the necessary environment for the creation of Majorana particles.

The precise arrangement of atoms in these materials is critical to the functionality of the qubit. Microsoft has developed advanced techniques so that atom by atom can be made, ensuring high-quality qubits.
