The world's most powerful quantum error decoder.

Large scale quantum computers will generate terabytes of syndrome data every second that must be decoded as fast as it’s acquired to stop errors propagating and rendering calculations useless.

To tackle this challenge, we’ve created Deltaflow.Decode, the world's most powerful scalable quantum error decoder. Customisable to each quantum computer maker's requirements, Deltaflow.Decode can be tightly integrated with any qubit control system to implement a complete high-speed quantum error correction cycle.

Deltaflow.Decode is the product of ground-breaking research into quantum error correction (QEC) by the world’s top experts in decoding, noise modelling and chip design.

Our approach

We use a robust process and a powerful set of tools to create decoders tailored to each quantum computer maker’s hardware.

Using prototyping and simulation to validate the design at every step, we start by modelling the decoder in pure software, then move to software modelling of a decoder chip, before creating a physical chip and integrating it inside the quantum computer.

The result is a high-performance decoder that delivers significant improvements over existing state-of-the-art Union Find decoders that can process more syndrome data more accurately and more quickly using smaller and more power efficient devices.
