Query: Splitting a single Cooper-pair with microwave light   We measure an aluminum superconducting double quantum dot and find that its
electrical impedance, specifically its quantum capacitance, depends on whether
or not it contains a single broken Cooper pair. In this way we are able to
observe, in real time, the thermally activated breaking and recombination of
Cooper pairs. Furthermore, we apply external microwave light and break single
Cooper pairs by the absorption of single microwave photons.
