⚛️ What Is the Majorana 1 Chip?
- Developer : Microsoft, announced in February 2025.
- Core Technology : Uses topological qubits based on Majorana zero modes , exotic quantum states that are more stable than conventional qubits.
- Material Basis : Built with a hybrid of indium arsenide and aluminum that supports superconductivity at ultra-low temperatures.
- Capacity : Early prototypes fit about 8 qubits , but the design aims to scale up to millions of qubits on a single chip.
- Goal : To overcome the biggest challenge in quantum computing—error correction—by making qubits inherently resistant to noise and instability.

🔬 Why Topological Qubits Matter
- Regular qubits : Extremely fragile, prone to errors from tiny environmental disturbances.
- Topological qubits : Encode information in a way that is protected by the topology of the system, making them far less error-prone.
- Analogy : A regular qubit is like a delicate snowflake that melts easily, while a topological qubit is like a knot in a rubber band—it stays intact even when stretched.
- Impact : This stability is crucial for building fault-tolerant quantum computers that can perform reliable calculations at scale.
