ETH Zurich demonstrates 17,000 qubit array with 99.91% fidelity (ethz.ch)

• Successfully operated a 17,000-qubit integrated array.
• Maintained 99.91% operational fidelity, minimizing error correction overhead.
• Sets a new benchmark for scalable, high-stability quantum processors.

"Researchers at ETH Zurich have demonstrated a massive leap in quantum scaling by operating a 17,000-qubit array with a record-high 99.91% operational fidelity. This breakthrough addresses the primary bottleneck in quantum computing: maintaining stability while increasing qubit counts. By achieving near-perfect gate performance at this scale, the team has significantly lowered the overhead required for quantum error correction. This development is a critical step toward functional, industrial-scale quantum applications, enhancing Europe's strategic position in sovereign computational infrastructure and future-proof cryptography."
