Are quantum computers arriving in 10 years?

The Quantum Breakthrough Timeline

A new Nature analysis argues that recent breakthroughs are tightening the path to practical quantum computers, with "useful" machines possibly arriving within roughly a decade.

Why Now Is Different

Compounding advances: Progress in error correction, device stability, and system engineering are multiplying each other's impact.

From theory to testable: What felt theoretical is becoming a set of increasingly buildable milestones.

The Impact

If quantum advantage becomes real in the 2030s, industries like cybersecurity, materials science, drug discovery, and logistics could face discontinuities. This raises urgency for "quantum readiness"—especially in cryptography.
