Quantum Computing Revisited

Quantum error correction is showing real progress. Larger systems are now demonstrating improved reliability for quantum information.

This is a key step, but commercial viability hinges on more than just technical gains. Demonstrating a clear advantage over classical computing is essential for creating economic value.

Significant hurdles remain, including scaling up systems, choosing between competing architectures, and justifying the high infrastructure costs for specific applications. The path to widespread practical use is still unclear.
