Microsoft Majorana 1 Quantum Chip

Topological Qubits
Microsoft’s Majorana 1 adopts a radically different approach, utilizing topological qubits based on Majorana fermions—quasiparticles that encode quantum information non-locally, inherently protecting it from decoherence. The chip’s “Topological Core” integrates indium arsenide-aluminum hybrid nanowires arranged in an H-shaped lattice, with each H structure hosting four Majorana zero modes to form a single qubit. This architecture leverages a newly developed “topoconductor” material stack, fabricated atom by atom to stabilize Majorana states. Unlike superconducting qubits, Majorana 1’s topological qubits are controlled digitally via voltage pulses, eliminating the need for analog tuning and simplifying scalability. While the current iteration contains only eight qubits, its modular design allows tiling across the chip, theoretically supporting a million-qubit system.
