Welcome to QMiCS – a European Quantum Flagship project
QMiCS sets up a quantum microwave local area network cable over a distance of several meters. We will use this architecture to implement quantum communication protocols such as teleportation between two superconducting quantum nodes.
Since our approach does not require any of the notoriously loss‑prone frequency conversion techniques, our platform will be highly beneficial for distributed quantum computing.
In addition, we take first steps towards the ambitious goal of radar-style quantum sensing with microwaves. Major milestones here are the implementation of microwave single photon detectors and the development of a roadmap towards commercial applications in later phases of the Flagship.
The mission of QMiCS is to combine European expertise and lead the efforts in developing novel components, experimental techniques, and theory models building on the quantum properties of continuous-variable propagating microwaves.
QMiCS’ long-term visions are (i) distributed quantum computing & communication via microwave quantum local area networks (QLANs) and (ii) sensing applications based on the illumination of an object with quantum microwaves (quantum radar). With respect to key quantum computing platforms (superconducting circuits, NV centers, quantum dots), microwaves intrinsically allow for zero frequency conversion loss since they are the natural frequency scale. They can be distributed via superconducting cables with surprisingly little losses, eventually allowing for quantum communication and cryptography applications.
Radar works at gigahertz frequencies because of the atmospheric transparency windows anyways.
Scientifically, QMiCS targets a QLAN demonstration via quantum teleportation, a quantum advantage in microwave illumination, and a roadmap to real-life applications for the second/third phase of the QT Flagship.
Beneath these three grand goals lies a strong component of disruptive enabling technology provided by two full and one external industry partner: the development of a microwave QLAN cable connecting the millikevin stages of two dilution refrigerators, improved cryogenic semiconductor amplifiers, and packaged pre-quantum ultrasensitive microwave detectors.
The resulting “enabling” commercial products are beneficial for quantum technologies at microwave frequencies in general.
Finally, QMiCS fosters awareness in industry about the revolutionary business potential of quantum microwave technologies, especially via the advisory third parties “Airbus Defence and Space Ltd” and “Cisco Systems GmbH”. In this way, QMiCS helps placing Europe at the forefront of the second quantum revolution and kick-starting a competitive European quantum industry.
