Superconducting microfabricated ion traps
We fabricate superconducting ion traps with niobium and niobium nitride and trap single S88r ions at cryogenic temperatures. The superconducting transition is verified and characterized by measuring the resistance and critical current using a four-wire measurement on the trap structure, and observing change in the rf reflection. The lowest observed …
