Fermilab’s Underground Facilities for Quantum Sensing


Code of conduct: The Wine and Cheese is a scientific seminar and thus questions and discussion are welcome. The goal of discussion is to enhance the quality and understanding of the science for the whole community. Out of consideration for all, even when questions are not straightforward, we will insist that they be asked and answered with respect and civility. We value voices of all backgrounds, accents, pitches and degrees of softness, both among our speakers and in the audience. Scientific claims are judged by their content and rigor, and not by the demeanor of their proponent

      Recent measurements have demonstrated that superconducting qubit decoherence is affected by radiation. As a result, many groups around the world are working to better understand the relationship between different types of radiation and qubit response. This crucial to quantum error correction because radiation can cause correlated loss of information across multiple qubits, defeating error correction algorithms. Additionally, the fundamental energy scale at which superconducting qubits operate may enable their development as meV-scale detectors for HEP applications, such as the direct detection of dark matter. Here at Fermilab, we have two world-class underground facilities which are already being used to study this problem: NEXUS and QUIET. I will talk about the program’s plans for the next few years and forecast some first results from a qubit operated underground.
