The quest to harness the power of quantum computing has taken a pivotal step forward with the development of a revolutionary new chip that converges electronics and light using cutting-edge Germanium-silicon technology. Backed by a €3 million investment from the European Commission, the ONCHIPS consortium is pioneering a novel approach to quantum hardware, leveraging the unique properties of hexagonal Germanium-Silicon to create a scalable, efficient, and faster quantum computer.
By integrating spin qubits for computation and photonics for communication on a single chip, this innovative technology has the potential to overcome the scalability hurdles that have long plagued quantum computing, unlocking new avenues for breakthroughs in fields such as drug discovery, cybersecurity and artificial intelligence.
As Europe’s quantum ecosystem converges with its established semiconductor industry, the ONCHIPS project is poised to bolster the continent’s technological sovereignty, paving the way for the widespread adoption of quantum technologies and cementing its position at the forefront of scalable quantum systems.
Introduction to Quantum Computing Roadblocks
Quantum computers have the potential to revolutionize various fields such as drug discovery, cybersecurity, and artificial intelligence by solving complex problems that are currently unsolvable with traditional computers. However, the development of quantum computers is hindered by several roadblocks, including the scalability of qubits, which are the fundamental building blocks of quantum computers. The European Commission has invested €3 million in a project called ONCHIPS to develop a new type of quantum chip that combines electronics and light using advanced Germanium-Silicon technology.
The goal of the ONCHIPS project is to create a quantum chip that can overcome the current limitations of qubits, enabling the development of faster, more efficient, and scalable quantum computers. The project consortium brings together leading institutions from across Europe to drive technological independence and quantum innovation. By developing a new type of quantum hardware, the ONCHIPS project aims to make quantum computers more practical for real-world applications and enable them to solve some of the most challenging problems faced by society today.
The development of quantum computers is a complex task that requires the integration of various components, including qubits, communication pathways, and supporting electronics. The ONCHIPS project uses a monolithic integration technique to fit all these components onto a single piece of material, making it easier to scale up the production of quantum chips. This approach has the potential to reduce the size and complexity of quantum systems, making them more practical for real-world applications.
Quantum Computing Scaling Problem
One of the major challenges facing the development of quantum computers is the scalability of qubits. As the number of qubits increases, the complexity of the system also increases, making it harder to control and manipulate the qubits. The ONCHIPS project aims to address this challenge by developing a new type of qubit that can be easily scaled up. The project uses a special version of Germanium-Silicon material that has a hexagonal, honeycomb-like arrangement of atoms, which makes it better at emitting light.
Using hexagonal Germanium-Silicon material in quantum computing is a new approach that has not been explored before. Scientists have worked with cubic Germanium-Silicon for years and even built qubits using it, but this special version of the material has never been used in a real quantum computer. The ONCHIPS project aims to change this by developing a new type of qubit that can be easily integrated into a silicon-based platform.
The scalability of qubits is critical to the development of practical quantum computers. As the number of qubits increases, the system’s computational power also increases, enabling it to solve more complex problems. The ONCHIPS project aims to develop a new type of qubit that can be easily scaled up, making it possible to build larger and more powerful quantum systems.
All-In-One Silicon Platform
The ONCHIPS project uses a monolithic integration technique to fit all the components of a quantum system onto a single piece of material. This approach has several advantages, including reducing the size and complexity of the system, making it easier to scale up the production of quantum chips. The use of a silicon-based platform also makes it possible to integrate quantum components with CMOS-compatible Germanium-Silicon, which is a widely used material in the semiconductor industry.
The development of an all-in-one silicon platform for quantum computing has the potential to revolutionize the field. By integrating all the components of a quantum system onto a single piece of material, it becomes possible to build larger and more powerful quantum systems that can solve complex problems. The ONCHIPS project aims to develop a new type of quantum chip that can be easily integrated into a silicon-based platform, making it possible to build practical quantum computers.
The use of CMOS-compatible Germanium-Silicon material in the ONCHIPS project also has the potential to reduce the cost of producing quantum chips. By using a widely used material in the semiconductor industry, it becomes possible to leverage existing manufacturing infrastructure and expertise, reducing the cost and complexity of producing quantum chips.
Strengthening Europe’s Quantum Independence
The ONCHIPS project aims to strengthen Europe’s quantum independence by developing a new type of quantum chip that can be produced domestically. The project brings together leading institutions from across Europe to drive technological independence and quantum innovation. By developing a new type of quantum hardware, the ONCHIPS project aims to reduce reliance on imported advanced chips for quantum technologies and contribute to Europe’s goal of technological sovereignty.
The success of the ONCHIPS project has the potential to position Europe as a pioneer in scalable quantum systems. By developing a new type of quantum chip that can be easily integrated into a silicon-based platform, the project aims to make quantum computers more practical for real-world applications. The use of CMOS-compatible Germanium-Silicon material also makes it possible to leverage existing manufacturing infrastructure and expertise, reducing the cost and complexity of producing quantum chips.
The ONCHIPS project is set to conclude in 2026 and brings together a consortium of leading European organizations. The partners include Universiteit Twente in the Netherlands, which coordinates the project, along with Technische Universiteit Eindhoven (Netherlands), Technische Universität München (Germany), Centre National de la Recherche Scientifique (CNRS) (France), Universität Konstanz (Germany), Budapesti Műszaki és Gazdaságtudományi Egyetem (Hungary), and the Dutch company Single Quantum BV.
