Alice & Bob taps Riverlane for error corrected quantum computer
Riverlane and Alice & Bob have teamed up to work on error corrected quantum computer systems.
The collaboration will see the integration of the Riverlane quantum error correction (QEC) stack within the larger quantum computer system based on cat qubit technology developed by Alice & Bob in France.
Alice & Bob has pioneered the cat qubit, a unique type of superconducting qubit that is protected from bit-flips by design, reducing the scale of the error correction challenge. This would allow the company to build a large-scale error-corrected quantum computer using 200 times fewer hardware resources than other state-of-the-art approaches. Last week, the company also showed much more stable qubits, with a lifetime of 10s rather than 10ms.

All quantum computers today, regardless of qubit type, require error correction technology that addresses both bit and phase flip errors in real time. Today’s best quantum computers perform thousands of reliable quantum operations. This must scale to a million and, ultimately, trillions of operations to execute those applications that will transform whole industries.
Riverlane, based in the UK, has developed a patented quantum error correction stack called Deltaflow that addresses this challenge as a distinct layer within a quantum computer’s overall stack via a quantum error decoder. The company is one of 27 recently selected by the European Innovation Council for its scale up programme.
“Our cat qubits are protected from one of the two errors in quantum computer systems. But this only solves part of the challenge.” said Dr. Théau Peronnin, Alice & Bob CEO. “We need quantum error correction to get rid of the remaining error, the phase-flip. We are partnering with Riverlane because they have the most promising QEC technology for this challenge.”
“We’re excited to begin exploring how best to combine Alice & Bob’s cat qubits, which are already one of the most resistant to errors, with our leading quantum error correction technology, to accelerate our shared path to fault-tolerant quantum computing. I’m certain this approach can help them scale further and faster,” said Riverlane’s Founder and CEO Dr. Steve Brierley.
