Last November, the company reported a 25x improvement.

The technology behind these demonstrations will be revealed at the APS March Meeting physics conference being held in Chicago on 14–18 March.

The underlying software tools are available to quantum computing researchers and developers in Q-Ctrl's products including Boulder Opal.

Most quantum computers are so error prone that only short, simple algorithms can be run, so they are not very useful.

Q-Ctrl found ways that AI and automation could be used to reduce errors in quantum logic elements as well as those that only arise when executing complete algorithms.

The company has shown that it could achieve up to 9000x performance improvements as measured by benchmarks from the US Quantum Economic Development Consortium.

"[European quantum startup] BEIT has been pushing the limits on quantum algorithms but has faced the same barriers as everyone else in hardware performance," said BEIT CEO Paulina Mazurek.

"We were impressed by how Q-Ctrl has opened totally new frontiers in our research and is bringing quantum advantage closer, enabling results better than classically possible for one of the cornerstone quantum algorithms. In some cases this software fundamentally transformed hardware, allowing results deemed impossible by previous benchmarks."

BEIT was an early user of Q-Ctrl's technology.

Q-Ctrl's results were achieved using conventional cloud access to commercial quantum computers, with no special access to hardware required, proving these capabilities can be delivered to any quantum computer user with an internet connection.

"Our benchmarking experiments demonstrate that there's hidden performance inside today's quantum computers that can become available with the right error-correcting software tools - no changes to hardware are needed," said Q-Ctrl founder and CEO Professor Michael J. Biercuk.

"We're excited to offer this technology to researchers, end users, and manufacturers worldwide to accelerate the path to quantum advantage and bring real-world applications closer to fruition."
