QLSI

The overall objective of this 4-year project is to demonstrate that spin qubits are a compelling platform for scaling to very large numbers of qubits. QLSI comprises the demonstration of four essential ingredients:

  • fabrication and operation of 16-qubit (16Q) quantum processors based on industry-compatible semiconductor technology
  • high-fidelity (>99%) single- and two-qubit gates, read-out and initialization with these devices in a lab environment
  • a quantum computer prototype, with online open access for the community, targeting 8qubits (8Q) available online, and integrating such a high-quality quantum processor into a high-performance computing environment
  • documentation of the detailed requirements to address scalability towards large Systems >1000qubits

QLSI lays the European foundation for industrial-scale implementations of semiconductor quantum processors. The project represents the ramping up of a dedicated effort across all leading European groups in the field of spin qubits to develop complete processor systems that are capable of reaching the level of thousands of qubits - a level widely believed to be necessary to show the potential for universal, error-corrected quantum computing.
