Alice & Bob Demonstrates GPU Decoding for LDPC-Cat Codes via NVIDIA NVQLink
Alice & Bob demonstrated decoding of its LDPC-cat error correction architecture on NVIDIA GPUs linked via NVQLink, achieving microsecond-scale communication between quantum control systems and classical GPU hardware. The demonstration combines cat qubits with two-dimensional LDPC codes, aiming at low-latency error correction cycles.

Within two years, the GPU decoding path could be integrated into Alice & Bob's next-generation control stack, enabling repeated real-time correction cycles for LDPC-cat logical qubits.
The microsecond-scale NVQLink interface removes the classical communication bottleneck that usually prevents decoders from keeping up with quantum error correction cycles. If the decoder throughput scales with larger code distances on available GPUs, Alice & Bob can close the feedback loop in hardware experiments before qubit coherence is lost.
