SPECTRUM

Making commercial Quantum Computer possible

Despite high expectations and numerous announcements made over the past ten years, the spread of Quantum Computers (QCs) is still in its infancy. The major factors limiting the diffusion and market penetration of QCs are their low scalability and high cost. Both issues are connected to the bulkiness and complexity of the signal lines that operate the QC. The required large amount of cables undermines the scalability and decreases the thermal stability of the Quantum Processing Units (QPUs). With the EU funded SPECTRUM project, we will develop a field-effect switch based on superconducting materials, which will substitute most of the cables (input and output) needed inside the cryostat of a QC, allowing a broader QCs diffusion.

Technology

Network switch for QC

The Quantum sUpErconducting SwiTch (QueSt), which we will develop and validate through SPECTRUM, is an innovative network switch, specifically designed for Quantum Computing. The core component of QueSt is an all-metallic superconducting transistor controlled via gate voltages. Our switch offers major advantages compared state-of-the-art switches, in terms of its higher operational frequency , shorter switching time and smaller power dissipation.
