2022年12月5日 · Aaron Chou, a senior scientist at Fermilab, works on detecting dark matter through quantum science. As part of DOE’s Office of High Energy Physics QuantISED program, he has developed a way to use qubits, the main component of quantum computing systems, to detect single photons produced by dark matter in the presence of a strong magnetic field.

2021年1月18日 · Precision measurement techniques harnessing ideas developed in the atomic, optical, and quantum sensing fields have increasingly been deployed in the search for dark matter (see e.g. [9, 10] for reviews). In this white paper, we discuss approaches to searching for dark matter using massive, mechanical sensing devices.
