QLS Logo

Bull is proud to be a key industrial partner in QLSI2 (Quantum Large‑Scale Integration with Silicon 2), a major European research initiative funded under the Horizon Europe program. This strategic collaboration unites 23 leading organisations from 9 countries with the shared ambition to accelerate Europe’s capabilities in scalable quantum computing. 

QLSI2 aims to design, build and demonstrate a semiconductor‑based quantum computer with up to 200 qubits, accessible via the cloud, by the end of 2027. Beyond hardware development, the project focuses on delivering meaningful use cases that show how quantum processors can solve real‑world problems, and on defining a robust industrial roadmap to enable future large‑scale deployment. 

 

Our role

Bull Powers Quantum Software Innovation

As part of this project, Bull is developing cutting-edge software tools that enable practical quantum applications.

Bull’s Contributions: Noise-Aware Compiler and Emulator

To make QLSI2’s quantum processors truly usable, Bull is building:

  • Noise-Aware Quantum Compiler – Converts high-level quantum algorithms into optimized instructions while accounting for hardware noise, ensuring higher fidelity and more reliable computation on real quantum devices.
  • Quantum Emulator – Simulates QLSI2 hardware, allowing researchers to test and validate algorithms in a realistic, noise-aware environment before deploying them on actual quantum processors.

Impact

By integrating noise-awareness into the software stack, Bull ensures that quantum applications can run efficiently and accurately, even on early-generation hardware. This work accelerates algorithm development, strengthens hardware-software integration, and positions Europe at the forefront of scalable quantum computing.
