University of Strathclyde Tests Wireless Control of Quantum Readout

Researchers from the University of Strathclyde, the University of Glasgow, and the National Physical Laboratory have demonstrated wireless communication with a superconducting microwave resonator at millikelvin temperatures, a challenging feat given the extreme cold required for most quantum hardware. The work directly addresses the limitations imposed by the dense network of electrical interconnects that currently hinder the scalability of quantum computers, moving beyond simply reducing wires to tackling the problem within dilution refrigerators. By comparing wired and wireless operation within the same cryogenic environment, the team revealed parasitic electromagnetic pathways arising from stray radiation within the cryostat enclosure. These results establish a framework for…
