Day 915: Two-Qubit Rydberg Gates

Day 915 of 2,016~19 min read

Learning Objectives

•**Implement CZ gates** using Rydberg blockade dynamics
•**Analyze the controlled-phase mechanism** from blockade-induced phases
•**Design Rydberg-dressed gates** for continuous two-qubit coupling
•**Construct native CCZ gates** exploiting multi-atom blockade
•**Calculate gate fidelities** limited by Rydberg decay and motional effects
•**Optimize pulse sequences** for high-fidelity entangling operations
