The brief

Analyst view

• Deltaflow decoders run with Infleqtion, OQC, Rigetti and Oak Ridge; over 20 makers and labs work with it.
• Dec 2025: adaptive hardware decoder, under 1 µs per round, cuts qubit overhead by up to 75% (Nature Comms).
• Mar 2026 roadmap: a million error-free operations before 2030, a trillion from about 2033.

Technical approach

As reported

Decoding

Reading the error checks

Error-correcting codes measure check qubits every round; a decoder infers from that stream which qubits actually went wrong.

Hardware

Decoders on FPGAs

Deltaflow runs on FPGA chips so each round is decoded in under a microsecond, keeping pace with the qubits instead of falling behind.

Adaptive

Decoders that learn the noise

The Local Clustering Decoder adapts to leakage, qubits slipping out of their 0/1 states, reaching target accuracy with far smaller codes.

Open tools

Deltakit

An open-source kit lets teams simulate and test error-correction schemes before running them live on hardware.
