Ultrafast current pulses let scientists push superconductors beyond their usual experimental limits before vortices and heat could interfere.

The method revealed striking differences in how two superconducting materials break down and could expose quantum behavior that conventional measurements miss.

Superconductivity is one of the most remarkable behaviors found in quantum materials. When some materials are cooled below a specific transition temperature, their electrical resistance disappears, allowing current to move through them without losing energy as heat.
