💻 Quick Start

🎯 Example 1: Pauli Network Synthesis

import quantic_rust
from quantic_rust import Metric

# 🔧 Synthesize a Pauli Rotation Network
circuit = quantic_rust.pauli_network_synthesis(
    ["XYZI", "IZYX", "XIYI"], 
    metric=Metric.DEPTH
)

# ⚡ Apply Full Optimization Pipeline
optimized = quantic_rust.full_optimize(circuit)

# 📊 Analyze Resource Consumption
stats = quantic_rust.analyze_circuit(optimized)
print(f"Total Gates: {stats['count']} | T-Depth: {stats['t_depth']}")

🎯 Example 2: Quantum Fourier Transform

import quantic_rust

# Create QFT circuit for 4 qubits
qft_circuit = quantic_rust.create_qft(n_qubits=4)

# Optimize for hardware
optimized_qft = quantic_rust.full_optimize(qft_circuit)

# Get circuit statistics
stats = quantic_rust.analyze_circuit(optimized_qft)
print(f"Depth: {stats['depth']} | CNOT Count: {stats['cnot_count']}")

🎯 Example 3: VQE Setup

import quantic_rust

# Define molecular Hamiltonian
hamiltonian = quantic_rust.create_hamiltonian([
    ("ZZ", 0.5),
    ("XI", 0.3),
    ("IX", 0.3)
])

# Create UCCSD ansatz
ansatz = quantic_rust.create_uccsd_ansatz(n_qubits=4, n_electrons=2)

# Initialize VQE
vqe = quantic_rust.VQE(hamiltonian, ansatz)
result = vqe.minimize()

print(f"Ground State Energy: {result.energy}")
