Inverse Engineering Quantum Control

Overview

Methodology for designing control protocols in multi-ion quantum devices where one ion acts as a "classical" piston driven by Coulomb interaction with another ion whose quantum motion is controlled via trapping potential modulation.

Paper: arXiv:2606.03488 (Li et al., 2026)

Core Methodology

1. Self-consistent stationary state: Determine stationary state accounting for quantum effects in the coupled ion system
2. Quantum regime identification: Find narrow quantum ground state connecting two broad classical regimes
3. Inverse engineering: Design control protocols for classical ion motion by working backwards from desired trajectory to required potential modulation

Application Pattern

• Multi-ion quantum device control
• Quantum-classical transition studies
• Trapping potential modulation for quantum state control

Activation

Keywords: quantum control, two-ion device, inverse engineering, piston control, trapping potential modulation, quantum-classical transition, Coulomb interaction
