RESUMEN
OBJECTIVES: Attempts to reduce health inequities in England frequently prioritise some equity dimensions over others. Intersectionality highlights how different dimensions of inequity interconnect and are underpinned by historic and institutionalised power imbalances. We aimed to explore whether intersectionality could help us shed light on young adults' understanding of health inequities. STUDY DESIGN: The study incorporatedqualitative thematic analysis of primary data. METHODS: Online focus groups with young adults (n = 25) aged 18-30 living in three English regions (Greater London; South Yorkshire/Midlands; North-East England) between July 2020 and March 2021. Online semistructured interviews (n = 2) and text-based communication was conducted for participants unable to attend online groups. RESULTS: Young adults described experiencing discrimination, privilege, and power imbalances driving health inequity and suggested ways to address this. Forms of inequity included cumulative, within group, interacting, and the experience of privilege alongside marginalisation. Young adults described discrimination occurring in settings relevant to social determinants of health and said it adversely affected health and well-being. CONCLUSION: Intersectionality, with its focus on discrimination and identity, can help public health stakeholders engage with young adults on health equity. An upstream approach to improving health equity should consider multiple and intersecting forms of discrimination along with their cultural and institutional drivers.

Radiation sensors based on the heating effect of absorbed radiation are typically simple to operate and flexible in terms of input frequency, so they are widely used in gas detection1, security2, terahertz imaging3, astrophysical observations4 and medical applications5. Several important applications are currently emerging from quantum technology and especially from electrical circuits that behave quantum mechanically, that is, circuit quantum electrodynamics6. This field has given rise to single-photon microwave detectors7-9 and a quantum computer that is superior to classical supercomputers for certain tasks10. Thermal sensors hold potential for enhancing such devices because they do not add quantum noise and they are smaller, simpler and consume about six orders of magnitude less power than the frequently used travelling-wave parametric amplifiers11. However, despite great progress in the speed12 and noise levels13 of thermal sensors, no bolometer has previously met the threshold for circuit quantum electrodynamics, which lies at a time constant of a few hundred nanoseconds and a simultaneous energy resolution of the order of 10h gigahertz (where h is the Planck constant). Here we experimentally demonstrate a bolometer that operates at this threshold, with a noise-equivalent power of 30 zeptowatts per square-root hertz, comparable to the lowest value reported so far13, at a thermal time constant two orders of magnitude shorter, at 500 nanoseconds. Both of these values are measured directly on the same device, giving an accurate estimation of 30h gigahertz for the calorimetric energy resolution. These improvements stem from the use of a graphene monolayer with extremely low specific heat14 as the active material. The minimum observed time constant of 200 nanoseconds is well below the dephasing times of roughly 100 microseconds reported for superconducting qubits15 and matches the timescales of currently used readout schemes16,17, thus enabling circuit quantum electrodynamics applications for bolometers.
