The quantum-technology sector is burgeoning, but challenges remain when it comes to creating viable commercial products. While quantum sensors show great promise, some technologies rely on ultrahigh vacuum (UHV) – which is difficult to achieve in compact, portable devices. My guest in this episode of the Physics World Weekly podcast is Florence Concepcion , who focuses on the miniaturization of UHV systems for practical quantum sensors and other devices. She is a senior quantum engineer at Aquark Technologies – a UK-based company that is developing cold-matter quantum technologies. In 2025, Concepcion was awarded a £1.9M Innovate Future Leaders Fellowship by the UK government. She explains how that money will be spent over four years to develop vacuum systems for quantum technologies. Before joining Aquark, Concepcion did a PhD on a topic at the intersection of astronomy and atomic physics.…
