Inside CERN's quest to build a reliable quantum computing device, as it'll need 50-100 times more computing power to process Large Hadron Collider data by 2026
Quantum computers could help explain some of the most fundamental mysteries in the universe and upend everything from finance to encryption …
Context & Ripple Effects
CERN's problem is arithmetic, not hype: the Large Hadron Collider's data output will demand 50-100 times more computing power by 2026, and classical scaling alone may not close that gap — so the lab is trying to build a reliable quantum device itself rather than wait for one. The story lands amid a crowded field: an overview of the competing quantum approaches at IBM, Google, and Microsoft shows the same race from the vendor side.
What has changed since this reporting is that the vendors CERN would depend on have since published concrete roadmaps — IBM's plan for a 100,000-qubit machine within a decade and Intel's Tunnel Falls, a 12-qubit research chip for academic partners — turning CERN's 2026 deadline into a test of whether vendor timelines can serve real scientific workloads.
First-order effects
- CERN faces a hard procurement decision: its 2026 data-processing target forces investment in quantum reliability research now, pulling the lab into direct R&D rather than passive waiting on commercial machines.
Second-order effects
- Vendors gain a demanding anchor customer: a facility like CERN defines what 'reliable' must mean in practice, giving IBM, Intel, and rivals a benchmark workload to design against as they scale qubit counts.
Third-order effects
- If big-science deadlines keep setting the requirements bar, quantum computing shifts from demonstration projects to production infrastructure, with error rates and uptime — not raw qubit counts — becoming the metric that decides which approach wins.
The trend: Quantum computing is being pulled from laboratory curiosity toward mission-critical infrastructure by users with fixed deadlines, making reliability rather than qubit count the field's defining race.
