ETH Zurich Researchers Achieve 99.91% Precision in Quantum Swap Gates

4/12/2026

Summary

Story summary

Researchers at ETH Zurich developed a swap gate using neutral atoms with 99.91% precision across 17,000 qubit pairs.
Tilman Esslinger of ETH Zurich led the work, using geometric phases to resist noise rather than tunneling or collisions.
The approach enables simultaneous operations on multiple qubits, advancing quantum computing.
The findings were published in Nature.
Future steps include integrating these swap gates with a quantum gas microscope for selective qubit-pair manipulation.
