Circuit Optimizer

Purpose

Provides expert guidance on quantum circuit optimization techniques for reducing gate count, minimizing depth, and adapting circuits to hardware constraints.

Capabilities

• Circuit depth reduction algorithms
• Gate cancellation and merging
• Peephole optimization
• Template matching optimization
• Commutation analysis
• Hardware topology-aware routing
• Two-qubit gate minimization
• Compilation pass orchestration

Usage Guidelines

1. Analysis: Profile circuit for optimization opportunities (gate counts, depth, connectivity)
2. Gate Reduction: Apply cancellation and merging rules for equivalent gates
3. Depth Optimization: Parallelize independent operations where topology allows
4. Hardware Mapping: Route circuits to respect hardware connectivity constraints
5. Verification: Validate circuit equivalence after optimization
