Entangled Flying Electron Quantum Technology

The ELEQUANT project proposes a paradigm shift in quantum technology by exploiting flying qubits, presenting a transformative alternative to mainstream approaches such a superconducting or semiconducting qubits. While photon-based flying qubits face challenges in real-time manipulation and interaction due to their fast propagation speed and weak photon-photon interaction, ELEQUANT aims to harness the potential of electronic charges for superior scalability and connectivity. Through pioneering research in the manipulation of electronic wavepackets in semiconductor nanostructures, the project strives to achieve the ambitious goal of realizing high-fidelity flying charge qubits and demonstrating entanglement between them. Key objectives include the development of novel quantum materials platforms based on strained Ge and multi-layered graphene. By establishing a comprehensive roadmap for solid-state flying qubit technology, ELEQUANT seeks to accelerate innovation in quantum technology and foster collaborative partnerships with industry stakeholders on a European scale. With a focus on scalability, connectivity, and coherence, ELEQUANT aims to propel quantum technology into a new era of unprecedented capabilities and applications.
