Quantum Logic Spectroscopy

Spectroscopy of ions whose states cannot be read directly, mapped onto a co-trapped logic ion through shared motion.

Core Principles & Analysis

• Lasers are used to couple each ion's internal and external motional degrees of freedom.
• The remaining states are accessed by driving stimulated Raman spectroscopy transitions with a laser.
• Applied to molecular ions at NIST in 2017 for spectroscopy of species with no closed cycling transition.
