This review article examines the use of diamond-based quantum sensors, specifically nitrogen-vacancy (NV) centers in diamond, as diagnostic tools for studying superconductivity in materials under high-pressure conditions. The technique allows researchers to probe magnetic and electrical properties of potential high-temperature superconductors in diamond anvil cells, where traditional measurement methods face significant challenges. The authors discuss how these quantum sensors can detect weak magnetic fields and temperature variations at the micrometer scale, enabling precise characterization of superconducting transitions in compressed materials.
Why it matters
This technology addresses a critical measurement gap in high-pressure physics research, potentially accelerating the discovery and validation of room-temperature superconductors. Such advances could transform energy transmission, magnetic levitation systems, and quantum computing by enabling lossless electrical conduction at practical temperatures and pressures.
