Insights
This technical milestone in quantum error correction (QEC) represents a significant advancement in quantum computing development. The integration of Riverlane's decoder with Rigetti's 84-qubit system achieved sub-microsecond processing speeds, effectively solving the critical "backlog problem" that has been a major hurdle in QEC implementation.
The demonstration's key technical achievement lies in the real-time processing capabilities that operate faster than the 1 microsecond threshold for measurement data generation. Rigetti's superconducting qubit architecture, with gate speeds of 60-80 nanoseconds, provides a substantial advantage over ion trap and pure atom-based systems.
While promising for long-term quantum computing development, this advancement is still primarily experimental and likely won't translate to immediate commercial applications or revenue impact. However, it strengthens Rigetti's competitive position in the quantum computing space and demonstrates progress toward fault-tolerant quantum computing.
By integrating Riverlane’s quantum error decoder into the control system of Rigetti’s 84-qubit Ankaa™-2 system, the team was able to demonstrate real-time, low latency quantum error correction, a critical process for developing fault tolerant quantum computers
BERKELEY, Calif., Oct. 31, 2024 (GLOBE NEWSWIRE) -- Rigetti (Nasdaq: RGTI), a pioneer in full-stack quantum-classical computing, announced the successful demonstration of real-time and low latency quantum error correction on a Rigetti quantum computer.
Fault tolerance is the point at which lengthy operations can execute without a single error, due to the application of quantum error correction. Reaching this stage, and in turn realizing the full potential of quantum computers, will require the co-development of quantum error correction and quantum computing technologies. Rigetti and Riverlane’s recent work demonstrating real-time and low-latency quantum error correction on Rigetti’s 84-qubit Ankaa™-2 system is an important step in our journey towards developing fault tolerant quantum computers.
Among the quantum error correction resources being developed are classical algorithms that identify errors that occur during quantum computation. These classical algorithms are known as decoders. A challenge in improving the utility of decoders is addressing the problem of the backlog of computations that accumulates as the decoder processes data. To avoid the backlog problem, the decoding needs to occur at the same speed as the quantum circuit. This experiment demonstrated decoding times faster than the 1\unit\micro threshold for generating measurement data on a superconducting qubit device -- ensuring that the backlog problem is avoided and showcasing that low-latency feedback can be maintained during quantum error correction operations.
“High fidelities are not enough to make a quantum computer useful. There are a lot of classical computing components at play that make the system work, including with error correction. Our partnership with Riverlane to demonstrate quantum error correction technology integrated with our hardware is deeply important on our path towards fault tolerance,” says Dr. Subodh Kulkarni, Rigetti CEO. “A significant benefit of superconducting qubits is that we can attain much higher gate speeds than other modalities. Rigetti’s system gate speeds consistently achieve an active duration of 60-8ns, which is four orders of magnitude faster than systems based on ion traps and pure atoms. System speed is an important factor to enable hybrid computing with current CPUs/GPUs.”
“To execute quantum error correction (QEC) at scale, we need QEC to happen in real-time and on real hardware. Our latest experiment with Rigetti represents a significant step towards these crucial requirements. It demonstrates the ability of Riverlane’s QEC technology to integrate seamlessly with fast-feedback control systems, resulting in the world’s first low-latency QEC experiment. It’s an exciting mark of progress and will help unlock the next generation of quantum experiments that go beyond purely keeping logical qubits alive and into demonstrating the first building blocks of fault-tolerant quantum computing,” says Steve Brierley, Riverlane CEO.
Rigetti’s longtime partnership with Riverlane also includes collaborating on a 24-qubit Ankaa-class system at the UK’s National Quantum Computing Centre where Rigetti will be integrating Riverlane’s technology with the long-term objective of large-scale error correction.
