FeedbackGRAPE Tutorials

These tutorials demonstrate advanced feedback-based GRAPE techniques for enhanced quantum control with real-time optimization and adaptive protocols.

Note

These tutorials build upon the concepts from the basic GRAPE tutorials. We recommend completing those first if you’re new to GRAPE optimization.

State Preparation Examples

• A1. State preparation with Jaynes-Cummings controls for \( | 1 ⟩ + | 3 ⟩ \) fock state
• A2. State preparation with Jaynes-Cummings controls for 4-legged cat state
• C. State preparation from a thermal state with Jaynes-Cummings controls
• This is equivalent to Example C but contains only the code blocks as in the accompanying paper

State Purification

• B. State purification with qubit-mediated measurement

State Stabilization

• D. State stabilization in a noisy environment with Jaynes-Cummings controls
• E: State stabilization with SNAP gates and displacement gates
• Stabilization of 5 qubits using a RNN control model
