Caltech and Oratomic Introduce “Mitten” qLDPC Codes for High-Throughput Quantum Computing
Caltech and Oratomic have introduced a new family of quantum low-density parity-check (qLDPC) codes, named 'Mitten', aimed at enabling high-throughput quantum computing. The codes promise more efficient error correction, potentially lowering the physical qubit overhead required for fault-tolerant operations.

If the Mitten codes demonstrate practical connectivity and decoding requirements, they could be adopted in near-term error-correction demonstrations, reducing the qubit overhead needed for a logical qubit and accelerating the timeline for useful fault-tolerant operations.
qLDPC codes are already under active investigation for architectures with long-range connectivity, such as ion traps and neutral atoms. A code with lower overhead and high threshold could be tested on existing hardware within two years, and companies like Quantinuum and QuEra are actively building such systems.
