‘Superconducting puddles’: Diamond’s hidden networks could power future quantum chips

SMRTR summary

Scientists have discovered that diamond becomes superconducting through hidden microscopic "puddles" that connect to allow electricity to flow without resistance. These regions can be controlled by adjusting temperature, magnetic fields, and electrical currents, potentially enabling multifunctional quantum chips that combine light, spin, superconductivity, and magnetism in a single material.
