BioQL v5.0.1: Enterprise Quantum Computing with Full QEC Control

BioQL is a quantum computing framework specifically designed for bioinformatics
applications. It provides a natural language interface for quantum programming
and integrates with popular quantum computing backends.

🆕 NEW in v5.0.1 - AWS BRAKET EXAMPLES:
- **AWS Braket Setup Scripts**: Complete automated setup for Amazon Braket
- **Example Circuits**: Bell state, GHZ, and more in OpenQASM 3.0
- **Integration Guides**: Step-by-step AWS Braket + BioQL integration
- **Verified Results**: 100% quantum entanglement confirmed on SV1

🚀 FEATURES from v5.0.0 - FULL QEC CONTROL EDITION:
- **Full Qubit Management**: Control physical vs logical qubits explicitly
- **Advanced QEC Codes**: Surface Code, Steane Code, Shor Code implementations
- **Qualtran Visualization**: Resource estimation and QEC overhead graphs
- **Error Mitigation**: ZNE, PEC, readout calibration, symmetry verification
- **QEC Metrics**: Comprehensive fidelity and error rate tracking
- **Dynamic Pricing**: QEC overhead cost calculation with multipliers

Basic Usage:
    >>> from bioql import quantum, QuantumResult
    >>> from bioql.profiler import Profiler
    >>> from bioql.error_mitigation import mitigate_counts
    >>> from bioql.provenance import enable_compliance_logging
    >>> from bioql.benchmarks import quick_benchmark
    >>>
    >>> # Enable compliance logging
    >>> enable_compliance_logging()
    >>>
    >>> # Profile quantum execution
    >>> profiler = Profiler()
    >>> result = profiler.profile_quantum("dock aspirin to COX-1", api_key="bioql_...")
    >>>
    >>> # Apply error mitigation
    >>> mitigated = mitigate_counts(result.counts, num_qubits=4)
    >>>
    >>> # Run chemistry benchmark
    >>> benchmark = quick_benchmark("H2", backend="simulator")
    >>> print(f"Accuracy: {100 - abs(benchmark.relative_error):.1f}%")
    >>>
    >>> # Use circuit library
    >>> from bioql.circuits import VQECircuit, get_catalog
    >>> vqe = VQECircuit(hamiltonian="H2")
    >>> circuit = vqe.build(num_qubits=4, num_layers=2)

QEC Module Usage (NEW in v4.0.0):
    >>> from bioql import quick_chemistry_test, quick_qec_demo, demo_error_mitigation
    >>>
    >>> # OpenFermion: Quantum chemistry
    >>> h2 = quick_chemistry_test('H2')
    >>> print(f"Energy: {h2.energy_ground_state:.4f} Hartrees")
    >>> print(f"Accuracy: {h2.accuracy_percent:.1f}%")
    >>>
    >>> # Qualtran: QEC analysis & RSA ModExp
    >>> qec_result, rsa_result = quick_qec_demo()
    >>> print(f"Qubits: {qec_result.num_logical_qubits} → {qec_result.num_physical_qubits}")
    >>> print(f"RSA factorization cost: {rsa_result.qec_gates_cost}")
    >>>
    >>> # Advanced error mitigation
    >>> em = demo_error_mitigation()
    >>> print(f"Accuracy: {em.accuracy_original:.1f}% → {em.accuracy_mitigated:.1f}%")
