Developing Multi-Core Silicon-Based Quantum Processors

Project description

Scalable silicon-based quantum computing

Silicon-based technology revolutionised the world of computing by enabling the creation of microchips and high-speed data transmission. Logically, silicon qubit technology could do the same for quantum computing. However, the semiconductor industry’s techniques differ from the requirements of quantum computers. Leveraging existing silicon-based technology, the EIC-funded MCSquare project seeks to create a scalable computing architecture for use in high-performance quantum computing. To do so, it will develop a novel 4x4 multicore architecture designed to distribute error correction and improve fault tolerance. It will also produce a quantum processor demonstrator using fully depleted silicon on insulator technology that allows for the fabrication of high-quality qubits in a scalable and reproducible manner.

Objective

Silicon technology was the key to transforming classical computing into a massive industry. Could it play a similar role in quantum computing? Silicon qubits have several attractive features and can rely on a mature industry that has already mastered the intricacies of scaling. However, while scientific advances in silicon qubit technology have been encouraging, progress has been modest on the commercial front. This is the consequence of a rift between the techniques of the semiconductor industry and the requirements of quantum computers. At Siquance, we close this gap thanks to a ground-breaking semiconductor approach: Fully Depleted Silicon On Insulator (FDSOI) technology. FDSOI technology enables the fabrication of high-quality qubits in a scalable and reproducible manner. Now, we advance these developments to the market. This project aims at delivering an FDSOI-based quantum processor demonstrator with a novel 4X4 multi-core architecture.
