Backend Selector

Purpose

Provides expert guidance on comparing and selecting quantum backends across multiple providers based on circuit requirements and performance criteria.

Capabilities

• Backend capability comparison
• Queue time estimation
• Cost optimization
• Fidelity-based ranking
• Connectivity analysis
• Job prioritization
• Provider API integration
• Historical performance tracking

Usage Guidelines

1. Requirements Analysis: Determine circuit qubit and gate requirements
2. Backend Query: Fetch available backends from all providers
3. Filtering: Eliminate backends that cannot support circuit
4. Ranking: Score backends by fidelity, queue time, and cost
5. Selection: Choose optimal backend for execution
