Strengths & Weaknesses

↑ Strengths

Integration with IBM Quantum hardware and simulatorsmedium

Support for quantum circuit design, simulation, and executionmedium

Optimization tools for compiling circuits to run on real devicesmedium

↓ Weaknesses

Steep learning curve for non-Python developershigh

API requires Python-specific patterns, TypeScript SDK is community-maintained

Frequent breaking changes between versionsmedium

v0.1 to v0.2 migration required rewriting chain definitions

Limited hardware access outside IBM Quantum ecosystemhigh

Primary integration is with IBM Quantum, other providers require additional setup or are not fully supported

Performance limitations in large-scale quantum circuit simulationmedium

Simulating circuits with high qubit counts on classical hardware can be resource-intensive and slow
