Microsoft Reveals '1,000x More Reliable' Quantum Chip as Bitcoin Threat Draws Nearer
Decrypt • • general
Key Points:
- Microsoft unveiled Majorana 2, a new topological quantum chip that is 1,000 times more reliable than its predecessor, achieving average qubit lifetimes of 20 seconds and some lasting up to one minute.
- The company credited its Microsoft Discovery platform and agentic AI tools for accelerating research by analyzing data, optimizing fabrication, and automating measurements to improve qubit reliability.
- Majorana 2 uses a lead-based superconductor design that better protects qubits from interference, advancing Microsoft's goal of scalable quantum computing by 2029.
- AI-driven automation significantly enhanced experimental efficiency by performing parallel voltage adjustments, surpassing human linear processing capabilities.
- The development raises concerns about "Q-Day," when quantum computers could break current cryptographic systems securing Bitcoin and other internet communications, potentially threatening billions in digital assets.
