Qblox is one of the members of the FERROMON project, a significant initiative under the EU Horizon 2020's Pathfinder program. This project aims to revolutionize quantum computing by developing scalable, efficient, and high-performance quantum computers. Qblox is collaborating with the University of Napoli, the Niels Bohr Institute in Copenhagen, QuantWare, and QuantrolOx to bring substantial advancements to the field.
The FERROMON project addresses key challenges in current quantum computing technology. Traditional superconducting qubits, essential for quantum processors, face issues related to connectivity, low two-qubit gate fidelity, drifting calibration parameters, and instability in qubit frequency. Our goal is to develop new superconducting qubits, called ferrotransmons and ferrogatemons, which can overcome these hurdles and enhance the scalability of quantum processors.
One of the main innovations in this project is the use of ferromagnetic Josephson junctions and semiconducting nanowire junctions instead of traditional Josephson junctions. These new types of junctions are designed to reduce the need for control lines, which currently present a significant bottleneck in scalability due to their associated heat dissipation and magnetic field induction.
The FERROMON project will explore two novel qubit designs. The first design involves integrating ferromagnetic Josephson junctions into a transmon geometry, resulting in "ferrotransmons." The second design hybridizes gatemons with π-junctions to create "ferrogatemons." These innovative qubit designs aim to eliminate the need for flux-bias lines, thereby reducing heat dissipation and improving qubit performance.
At Qblox, we will integrate these alternative qubit types into prototype full-stack systems. Our role involves testing the scalability and performance quality of these new qubit designs, ensuring they meet the demands of future quantum computing applications. The reduced hardware requirements and enhanced functionalities of these qubits are expected to make quantum processing units (QPUs) more scalable and efficient.
The FERROMON project's impact extends beyond immediate technological advancements. By addressing key issues in current quantum computing systems, we aim to create a sustainable and energy-efficient quantum computing platform. This aligns with the European sustainable development and green deal goals, promoting technologies that require fewer resources and consume less energy.
The FERROMON project represents a significant step forward in quantum computing. Through our collaboration, we aim to develop innovative qubit technologies that enhance the scalability and performance of quantum processors.
