Analysis
This paper investigates the generation of Dicke states, crucial for quantum computing, in qubit arrays. It focuses on a realistic scenario with limited control (single local control) and explores time-optimal state preparation. The use of the dCRAB algorithm for optimal control and the demonstration of robustness are significant contributions. The quadratic scaling of preparation time with qubit number is an important practical consideration.
Key Takeaways
- •Demonstrates time-optimal generation of Dicke states with limited control.
- •Employs the dCRAB algorithm for optimal control.
- •Shows quadratic scaling of preparation time with the number of qubits.
- •Highlights robustness of the control scheme.
