Phasecraft, a quantum algorithms company, has unveiled a quantum enhanced software platform which it claims can complete calculations 1,000 times faster than classical computers.

The development of the platform, called Mondrian, was initially funded via a £1.2 million Quantum Catalyst Fund award from the government and developed in collaboration with the UK’s National Energy System Operator (NESO).

Bristol- based Phasecraft said Mondrian demonstrates how classical and quantum computing can work together to tackle some of the most complex optimisation problems facing industries such as energy, finance, and logistics.

The company said that Mondrian uses its new “quantum-enhanced optimisation” approach in which the output of a quantum algorithm is used to accelerate an existing classical algorithm.

This enables high-quality results to be obtained from error-prone quantum computers, which Phasecraft said allows problems which are too large and complex to fit directly onto small-scale quantum hardware to be addressed.

The platform is already being tested by several industrial and academic partners.

Phasecraft said that testing demonstrates Mondrian delivers speed-ups of up to 1,000 times for optimisation problems in real-world use cases explored with NESO, including power exchange calculations, intentional islanding, and renewable resource placement.

When applied to energy networks, Phasecraft said Mondrian tackles one of the most pressing computational problems which is how to efficiently run increasingly complex energy grids as demand rises, renewable integration grows, and the cost of new infrastructure soars.

The company said that grid operators can use Mondrian to determine network efficiency, reduce energy losses, plan network expansion, and site renewables and sensors more effectively.

"With the launch of Mondrian, we take a major step toward commercial quantum utility, showing how enhanced quantum algorithms can unlock near-term breakthroughs across sectors that face large-scale optimisation problems.” said Ashley Montanaro, co-founder and chief executive of Phasecraft. “We’re rolling out secure access to Mondrian over the coming month and invite energy, infrastructure and logistics operators to reach out to get involved.”
