Infleqtion and Nvidia cut physical-to-logical qubit ratio

Infleqtion and Nvidia presented validated quantum error correction code: 98 physical qubits yield 18 logical qubits, about 5.4 physical qubits per logical at 18.4% encoding efficiency. It uses Infleqtion's open-source qLDPC library and Nvidia's CUDA-Q Logical layer.

• 98 physical qubits form 18 logical — 5.4 per logical qubit
• Encoding efficiency reaches 18.4%
• Code contains 49 X and 49 Z checks of weight six
• Uses Infleqtion's qLDPC and Nvidia's CUDA-Q Logical
