IQIT Project

The Integrated Quantum Information Technology (IQIT) project is an European collaboration with members from five different countries. Its aim is to develop and demonstrate novel routes towards scaling up physical devices for Quantum Information Science (QIS) with particular attention to communication between different parts of a quantum processor by means of quantum bus.

Developing a scalable technology will be pursued by first advancing two successful solid-state and atom-optical devices, namely arrays of superconducting qubits coupled to microwave resonators (here all-optical quantum computing will be explored for the first time in the microwave regime) and highly controlled ion trap systems, and then by combining them to yield a scalable basis for universal quantum computation and processing of quantum information.

This new, integrated scheme will be based on the simultaneous exploitation of superconducting qubits for fast and scalable computational tasks and of trapped ions for storage and processing of information with long coherence times. Integration between the solid-state and atomic devices will be carried out at all levels, including interactions, operations, measurement, control, and optimization. In the development of the project, experiment and theory will closely collaborate at all stages, and importantly, a close collaboration between hitherto mostly separately developing subfields of quantum information science (solid state and atomic-molecular optical physics) will be established allowing to combine the tremendous knowledge and expertise in both fields. The project's long-term vision is an integrated scalable device for QIS.

The breakthroughs envisioned are design, realization, and test of a four-qubit integrated processor with superconducting gates and trapped ions register, and, based on the knowledge gained here, the design of a scalable integrated architecture.
