Overview

• The team reports fault-tolerant operation in simulations even when inter-chip connections were up to 10 times noisier than on-chip operations.
• Models relied on the surface code to build reliable logical qubits from many physical qubits, reflecting current error-correction practice.
• Researchers ran thousands of tests across six modular designs using realistic parameters and tools from Google Quantum AI.
• The letter in Physical Review A, titled “Optimized noise-resilient surface code teleportation interfaces,” credits Mohamed A. Shalby with coauthors Leonid P. Pryadko, Renyu Wang, and Denis Sedov of the University of Stuttgart.
• The study, supported by the National Science Foundation and informed by prior MIT work, indicates engineers could link multiple small chips without waiting for perfect interconnect hardware.
