Project QLSI2 combines the expertise of 23 partners from 9 countries with the aim to demonstrate a cloud-accessible 200-qubit semiconductor-based quantum computer by the end of 2027. In addition, the consortium aims to demonstrate the implementation of meaningful use cases on their demonstrator.
The QLSI2 project will leverage the know-how of key European players (RTOs, academic laboratories, start-ups and large companies) in complementary areas of quantum technologies, from hardware to software, to define and implement a roadmap towards the project goal. The roadmap will extend its vision to the entire value chain, including the supply chain. Special attention will be paid to the industrialization of the proposed solution in order to keep Europe at the forefront of the race for quantum supremacy for a long time to come. The roadmap will be implemented considering both heterostructure-based and FD-SOI-based routes. In addition, and following these two routes, QLSI2 aims to advance both technology and manufacturing readiness to a level high enough to meet Europe’s ambitions for the industrialization of quantum technologies, with a particular focus on scalability.
QLSI2 continues the successful work of the previous QLSI project. QLSI has already advanced the state-of-the-art by demonstrating 3 entangled qubits in 6-qubit arrays, and has identified ways to reduce the impact of charge disorder that has hindered increasing the number of qubits. These results and the solid engineering ecosystem and mindset put in place (studying how to protect the qubits from ESD, developing calibration algorithms, RF controls, etc.) set the stage for QLSI2.
Fraunhofer IAF work on the statistical characterization of qubits at low temperatures to understand the variability aspects for later industrial production.
