Part 11/12:
As the race to create a fully functional quantum computer intensifies, Microsoft, Google, and IBM represent the leading contenders, each employing distinct strategies. Google previously declared "quantum supremacy," having completed a task faster than traditional supercomputers, though their qubit system necessitates a significant number of extra qubits for error correction. IBM continues to enhance its quantum chips but faces a similar challenge with error-prone superconducting qubits.
Microsoft’s commitment to leveraging naturally stable topological qubits distinguishes its approach, suggesting a potentially more efficient and reliable pathway towards realizing practical quantum computing.
