Deltaflow: The Quantum Error Correction Stack
Unlocking useful quantum computing
Deltaflow helps quantum computers accelerate their path to performance beyond the supercomputing threshold.
Today, the world’s best quantum computers can perform at most a few thousand reliable quantum operations (QuOps) before failure due to mounting data errors.
This must scale to millions of quantum operations (MegaQuOps) and ultimately trillions (TeraQuOps) for quantum computers to fulfil their vast potential.
Riverlane’s Quantum Error Correction (QEC) stack Deltaflow will unlock this opportunity. Deltaflow is a comprehensive QEC solution on a rapid path to utility scale. It includes qubit data readout, decoding, logical operations and orchestration.
Our Deltaflow roadmap will reach a MegaQuOp (a million real-time quantum operations) by 2026. This is the critical milestone when quantum computers reach sufficient scale to execute the first error corrected quantum applications.
How Deltaflow works
Deltaflow turns unstable physical qubits into error-free logical qubits. It has three main components working in a continuous cycle to process petabytes of data:
The world’s most powerful decoder. This identifies the errors in this data and sends corrective instructions.
Universal interface. This processes the qubit readout data from any quantum computer’s control system.
Orchestration layer. This coordinates and synchronises the complex activities in real time.

Our Decoder
The world's most powerful quantum error decoder sits at the core of Deltaflow. It optimally balances speed, accuracy and resource requirements.
The decoder gets broken up into many smaller sections. The data from the logical qubits is spread out across these sections and is processed in parallel to keep up with the huge number of qubit errors.

Riverlane's Quantum Error Correction Roadmap
We are building the world's first MegaQuOp scale QEC stack, capable of 1 million reliable quantum operations by the end of 2026.
Partnerships
We partner with the world’s leading quantum computer makers to implement Deltaflow. Our partner process has three steps:
- Work together to deeply understand their qubits, hardware, and error properties. We then design the best potential solutions, including the appropriate error correction codes and decoders.
- Test and implement QEC solutions offline in software.
- Test and implement real-time QEC solutions in hardware.
