About
The IBM Certified Associate Developer – Quantum Computation using Qiskit v0.2X validates foundational competency in quantum computing using IBM's open-source Qiskit framework. Launched in 2021, this certification was designed for developers beginning their quantum computing journey, demonstrating proficiency in defining, executing, and visualizing quantum circuits on IBM Quantum hardware and simulators. The certification covers Qiskit SDK v0.2X and was the entry-level quantum developer credential until its retirement on September 30, 2025. IBM released the successor certification (C1000-179) aligned with Qiskit v2.X in 2025; new candidates should pursue that credential. This certification remains valuable for historical reference and represents the foundational quantum developer skillset established during the early Qiskit ecosystem maturation.

Salary
| Region | Range | Notes |
|---|---|---|
| USD | $120,000 – $180,000 | Glassdoor Quantum Engineer ↗ · Robert Half Tech Salary Guide ↗ · Quantum is niche; range reflects 2–5 years experience. |
| ZAR | R480,000 – R850,000 | Approximate conversion (USD × 18). Limited region-specific data available. |
| GBP | £72,000 – £108,000 | IT Jobs Watch ↗ · Emerging specialist role; limited market data. |
| EUR | €82,000 – €125,000 | Quantum computing roles concentrated in research hubs (Germany, Netherlands). Limited salary data. |
| AUD | A$155,000 – A$220,000 | PayScale AU ↗ · Emerging market; data sparse. |
Salary note: Quantum computing is a niche, emerging field with limited job-market data. Ranges reflect academic research roles, IBM research labs, and early-stage quantum startups. Generalist quantum developers with 2–5 years experience command these ranges; specialized quantum algorithm designers may earn higher. Salary data for "Quantum Developer" specifically is limited; estimates use "Quantum Engineer" and "Research Scientist (Quantum)" as proxies.
