SuperQuLAN

Project Summary

A cool idea could lead to large interconnected quantum computing networks. When some metals are cooled to extremely low temperatures (close to 'absolute zero'), they become superconductors – their resistance to electron flow disappears. This lack of dissipation makes superconducting quantum circuits ideally suited for building large-scale quantum computing devices, where information processing is based on quantum bits (qubits) rather than binary digits (bits). However, the challenges imposed by the reliance on superconductivity and extreme cooling significantly hinder the implementation of local- and wide-area (LAN/WAN) networks connecting different devices and systems. The EU-funded SuperQuLAN project plans to remove this barrier with the demonstration of implementing LAN superconducting qubits in spatially separated refrigeration units connected via a cryogenic transmission line. Success will pave the way for larger metropolitan-area networks and open the door to internet connectivity for quantum computing devices.
