MCSquare: Developing multi-core silicon-based quantum processors

Without silicon, the classical computing industry would not have become the juggernaut it is today. Could the material play a similar role in quantum? Silicon qubits offer several attractive features, not least of which is a mature industry that has already mastered the ins and outs of scaling. And yet, while scientific advances around silicon qubits have been encouraging, progress has remained modest on the industrial front, mainly due to differences in semiconductor manufacturing techniques and quantum’s unique requirements.

Quobly is banking on an advanced semiconductor material, FD-SOI (fully-depleted silicon-on-insulator), to close this gap. FD-SOI and the associated very-large-scale-integration processes can be used to fabricate high-quality qubits in a scalable and reproducible manner.

The MCSquare project will result in an FD-SOI-based quantum processor demonstrator with a novel 4X4 multicore architecture.
