Quantum computing is having a moment. But the technology remains futuristic
Summary
Quantum computing is attracting major investment from big technology firms, governments, and startups, but it remains largely a research field with limited commercial revenue today. The article explains how quantum computers differ from classical systems and why they could eventually transform chemistry, materials science, and certain AI workloads. It also highlights the security implications, especially the threat to current encryption methods and the push toward post-quantum cryptography. Progress in error correction and scaling suggests the technology is advancing, but practical, widely useful quantum computers still appear years away.
