Microsoft Unveils Majorana 1 Chip for Next-Gen Quantum Computers

Microsoft has launched the Majorana 1 chip, which aims to advance quantum computing towards a million-qubit scale. This chip utilizes a new material called "topoconductor" for enhanced qubit stability.

Key points include:

  • Majorana 1 is positioned as a step toward practical and fault-tolerant quantum machines capable of solving large problems.
  • Concerns arise regarding potential impacts on cryptography, as quantum algorithms could threaten current encryption methods.
  • Google's Willow chip reportedly completed a task in under five minutes that would take a classical supercomputer 10 septillion years.
  • IBM is developing systems like Starling and Blue Jay to increase logical qubits and improve error correction over coming years.
  • Experts indicate that breaking Bitcoin’s elliptic-curve keys requires not only a significant number of physical qubits but also stable, error-corrected logical qubits and extensive processing time.
  • Estimates suggest millions or hundreds of thousands of physical qubits are necessary to target Bitcoin addresses effectively.

Graham Cooke highlights the vast combinations available in seed phrases, with a 24-word phrase offering significantly more security than a 12-word one, emphasizing that crypto wallets remain robust against immediate quantum threats.
