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.
Deltaflow.Decode can spot qubit errors quickly and accurately, and is designed to support the next generation of bigger and more powerful quantum computers.
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.
with lower power consumption
Deltaflow.Decode is a powerful quantum decoder technology, balancing speed and accuracy with resource requirements to provide a practical route to error-corrected quantum computing.
Introducing the world’s most powerful quantum decoder
The paper “A real-time, scalable, fast and highly resource efficient decoder for a quantum computer” explains how Riverlane’s latest quantum decoder balances the speed, accuracy, cost, hardware and power requirements to provide a practical route to error-corrected quantum computing.
Introducing the Riverlane Roadmap: Three basic steps to decoder success
Riverlane has announced a significant milestone in our development of the error correction stack for quantum computers. We have posted our first arXiv pre-print, which dives deep into our current generation decoder (DD1) for quantum error correction.
Riverlane announces world’s most powerful quantum decoder
Riverlane has developed the world’s first dedicated decoder chip and published its decoder IP and roadmap to early error-corrected quantum computing.
What is a TeraQuop decoder?
A TeraQuop decoder would enable a quantum computer to perform a trillion reliable operations – this is important because this represents the scale at which quantum computers start to solve problems that are intractable for any supercomputer.
Our world-leading team of researchers and engineers have decades of combined experience in the design and implementation of high speed, high performance error correction solutions.
Our dedicated noise team, led by Hari Krovi, builds circuit level noise models for our partners' quantum computing hardware, enabling us to create powerful and efficient decoders tailored to their qubits.
