In this episode of the Physics World Weekly podcast, we explore how computational physics is being used to develop new quantum materials; and we look at how ultrasound can help detect breast cancer.

Our first guest is <a href="https://cnqt-group.org/">Bhaskaran Muralidharan</a>, who leads the <a href="https://cnqt-group.org/">Computational Nanoelectronics & Quantum Transport Group</a> at the Indian Institute of Technology Bombay. In a conversation with Physics World’s Hamish Johnston, he explains how computational physics is being used to develop new materials and devices for quantum science and technology. He also shares his personal perspective on quantum physics in this International Year of Quantum Science and Technology.
Our second guest is <a href="https://www.npl.co.uk/our-people/profiles/dan-sarno">Daniel Sarno</a> of the UK’s <a href="https://www.npl.co.uk/">National Physical Laboratory</a>, who is an expert in the medical uses of ultrasound. In a conversation with Physics World’s Tami Freeman, Sarno explains why conventional mammography can struggle to detect cancer in patients with higher density breast tissue. This is a particular problem because women with such tissue are at higher risk of developing the disease. To address this problem, Sarno and colleagues have developed a ultrasound technique for measuring tissue density and are commercializing it via a company called <a href="https://www.npl.co.uk/sona">sona</a>.
