New EU Consortium Launches 4-year Quantum Scaling Project

(InsideHPC) A European consortium has been launched with the goal of scaling silicon quantum technologies. Named QLSI (Quantum Large-Scale Integration with Silicon), it’s a four-year four-year, €15 million ($17.7 million) EU project coordinated by CEA-Leti, the Grenoble, France-based electronics and IT research institute, and it aims to lay the foundation for industrial-scale semiconductor quantum processors.
The organization said the project will focus on demonstrating that “spin qubits” are the leading platform for scaling to large numbers of quantum bits, or qubits, the building blocks of quantum information processing.
The QLSI consortium brings experienced academics with knowledge of in silicon nanostructures and spin qubits, RTOs with silicon CMOS technology expertise, international businesses in the semiconductor and computing industries, as well as Europe’s quantum start-up sector.
Why the commitment to silicon? “Owing to their experience, the partners have already quantified promising single qubit performance: small size, high fidelity, fast read-out and manipulation,” stated the consortium. “Working with silicon, the next step is to leverage the vast infrastructure of the global semiconductor industry.”
QLSI will pursue four essential results:
Fabrication and operation of 16-qubit quantum processors based on industry-compatible semiconductor technology
Demonstration of high-fidelity (>99 percent) single- and two-qubit gates, read-out and initialization with these devices in a lab environment
Demonstration of a quantum computer prototype, with online open-access for the community, integrating such a high-quality quantum processor in a semi-industrial environment (up to eight qubits available online), and
Documentation of the requirements to address important issue of scalability towards large systems >1,000 qubits.
The project is an addition to the EU’s Quantum Flagship program, a 10-year, €1 billion ($1.18 billion) R&D initiative launched in 2018. It is a coherent set of research and innovation projects selected through a thorough peer-review process
