EU Sets Sail for Large-Scale Quantum Computing

Facebook X LinkedIn Email
Stemming from the EU’s Quantum Flagship 10-year, $1.18 billion (€1 billion) research and development initiative program launched in 2018, 19 companies and research institutions have joined forces for the QLSI (Quantum Large Scale Integration with Silicon) project. Information technology and electronics research institutes will lead the consortium, which is intended to last four years and to create the foundation for the EU’s industrial-scale implementation of semiconductor quantum processors.

The project is pursuing four essential results: the fabrication and operation of 16-bit quantum processors based on industry-compatible semiconductor technology; demonstration of high-fidelity (99%) single- and two-bit quantum gates and read out and initialization with these devices in a laboratory environment; demonstration of a quantum computer prototype integrated with such a high-quality quantum processor in a semi-industrial environment (with up to 8 qubits available online), with online open access; and documentation of the requirements to address the important issue of scalability toward large systems greater than 1000 qubits.

Partners, which include institutions such as IMEC, Fraunhofer Institute, CNRS, the University of Konstanz, and Leibniz-Institut, have already realized a number of key advances in the field of quantum silicon technology. CEA-Leti, for one, demonstrated a qubit manufactured by mass-production, CMOS technology in 2016.

Glossary
quantum
The term quantum refers to the fundamental unit or discrete amount of a physical quantity involved in interactions at the atomic and subatomic scales. It originates from quantum theory, a branch of physics that emerged in the early 20th century to explain phenomena observed on very small scales, where classical physics fails to provide accurate explanations. In the context of quantum theory, several key concepts are associated with the term quantum: Quantum mechanics: This is the branch of...
qubit
A qubit, short for quantum bit, is the fundamental unit of information in quantum computing and quantum information processing. Unlike classical bits, which can exist in one of two states (0 or 1), qubits can exist in multiple states simultaneously, thanks to a quantum property known as superposition. This unique feature enables quantum computers to perform certain types of calculations much more efficiently than classical computers. Key characteristics of qubits include: Superposition: A...
