…bility Fixes mit-han-lab#303 The old qiskit_aer.primitives.Sampler class has been deprecated and its constructor signature changed in newer Qiskit versions, causing the error: "Sampler.__init__() got an unexpected keyword argument 'options'" This change updates the import to use SamplerV2, which: - Supports the options parameter with backend_options - Is the recommended primitive for Qiskit Aer going forward - Maintains backward compatibility with existing code since we alias it as AerSampler 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
