Postprocess Counts

Apply post-processing to quantum measurement counts. This endpoint provides access to Haiqu's proprietary optimization algorithms for post-processing QAOA/VQE measurement results. All algorithm defaults are defined in haiqu-optimization. Users can override any parameter by passing it in the params dictionary. Args: request: PostprocessRequest containing: - lp_problem: QUBO problem serialized as LP file format - counts: Dictionary of bitstring -> count mappings - params: Optional parameters dict. Available options: * method (str): Post-processing method. Default: "bitflip_incremental" * reverse_string (bool): Whether to reverse bitstring ordering. Default: True * postprocess_iterations (int): Number of optimization passes. Default: 5 * use_fast_eval (bool): Enable fast evaluation. Default: True * seed (int): Random seed for reproducibility. Default: None Returns: PostprocessResponse with optimized costs and counts Raises: HTTPException: 400 if invalid problem format HTTPException: 500 if processing fails Example: { "lp_problem": "Minimize\n x0 + x1\nBinary\n x0\n x1\nEnd", "counts": {"00": 100, "01": 50}, "params": { "postprocess_iterations": 10, "seed": 42 } }
