Accelerating Commercial Quantum Computing via Self-Correcting Hardware

digitalTestedTRL 5

Imagine trying to write a letter where the ink disappears randomly; you'd need to write the same word a thousand times to be sure it's read correctly. This technology creates a 'smart' ink that fixes its own mistakes automatically. Because it handles its own errors, we can build a powerful computer using far fewer parts than current methods.

The business problem

What needed solving

Current quantum computers are too error-prone to run complex algorithms reliably. Fixing these errors usually requires an impractical number of physical qubits, delaying commercial viability by a decade.

The solution

What was built

A logical qubit demonstrator using a 1D chain of cat-qubits (3 data and 2 ancillary qubits) that automatically corrects bit-flip errors.

Who can put this to work

Pharmaceuticals
enterprise
Target: Drug discovery firm

If you are a drug discovery firm dealing with the inability to simulate complex molecules—this project developed cat-qubit technology that allows for reliable computations. This could enable the discovery of new molecules in minutes rather than billions of years.

Logistics
enterprise
Target: Global supply chain operator

If you are a global supply chain operator dealing with inefficient routing and delivery—this project developed a path to fault-tolerant quantum computers that can optimize supply chains. This hardware aims to be available in the cloud in 2-3 years.

Finance
mid-size
Target: Investment hedge fund

If you are an investment hedge fund dealing with volatile portfolio optimization—this project developed self-correcting qubits that reduce the physical hardware needed for a logical qubit from 1000 to fewer than 30. This accelerates the arrival of reliable quantum financial modeling.

Frequently asked

Quick answers

What is the cost or pricing for this technology?

Based on available project data, specific pricing for end-users is not provided, though the project received an EU contribution of EUR 2,500,000 for development.

Can this be scaled for industrial use?

Yes, the technology specifically reduces the hardware overhead required for a logical qubit from 900-1000 physical qubits to fewer than 30, making industrial scaling significantly more feasible.

What is the IP or licensing status?

Based on available project data, the technology is being developed by Alice & Bob, an SME, but specific licensing terms are not listed.

What is the timeline for commercial availability?

The company aims to have an error-corrected quantum computer available in the cloud in just 2-3 years.

How does this integrate with existing supercomputers?

The project aims to perform simulations that would take billions of years on the most powerful supercomputers in a matter of minutes.

Consortium

Who built it

The project is led by a single partner, Alice & Bob, which is a French SME. This 100% industry-led structure suggests a strong drive toward commercialization rather than academic research, focusing on a lean development cycle to beat global competitors.
