arvak 1.9.0

Arvak - Rust-native quantum compilation and orchestration platform for HPC with CUDA-Q, neutral-atom, and dynamic plugin support. Developed by The HAL Contract.

Arvak Python Bindings

Python bindings for the Arvak quantum compilation platform.

Installation

pip install arvak

Quick Start

import arvak

# Create a Bell state circuit
qc = arvak.Circuit("bell", num_qubits=2)
qc.h(0).cx(0, 1).measure_all()

# Check circuit properties
print(f"Depth: {qc.depth()}")
print(f"Qubits: {qc.num_qubits}")

# Convert to QASM
qasm = arvak.to_qasm(qc)
print(qasm)

# Parse QASM
qc2 = arvak.from_qasm("""
OPENQASM 3.0;
qubit[2] q;
h q[0];
cx q[0], q[1];
""")

Features

• Circuit Building: Fluent API for building quantum circuits
• Standard Gates: H, X, Y, Z, S, T, CX, CZ, and many more
• IQM Native Gates: PRX gate support
• QASM3 I/O: Parse and emit OpenQASM 3.0
• Compilation Types: Layout, CouplingMap, BasisGates for compilation
• Hamiltonian Simulation (arvak.sim): Trotter-Suzuki and QDrift time-evolution synthesis
• Variational Solvers (arvak.optimize): VQE, QAOA, PCE QUBO solver, spectral partition
• Noise Threading: NoisyBackend wraps any backend with a Qiskit noise model

Pre-built Circuits

# Bell state
bell = arvak.Circuit.bell()

# GHZ state
ghz = arvak.Circuit.ghz(5)

# Quantum Fourier Transform
qft = arvak.Circuit.qft(4)

Hamiltonian Simulation

from arvak.sim import PauliOp, HamiltonianTerm, Hamiltonian, TrotterEvolution

h = Hamiltonian.from_terms([
    HamiltonianTerm.zz(0, 1, -1.0),
    HamiltonianTerm.x(0, -0.5),
])
circuit = TrotterEvolution.new(h, t=1.0, n_steps=4).first_order()
counts = arvak.run_sim(circuit, shots=1024)

Variational Algorithms

from arvak.optimize import VQESolver, SparsePauliOp, QAOASolver, BinaryQubo

# VQE
h = SparsePauliOp([(-1.0, {0: "Z", 1: "Z"}), (-0.5, {0: "X", 1: "X"})])
result = VQESolver(h, n_qubits=2, n_layers=2, seed=0).solve()
print(result.energy)

# QAOA
qubo = BinaryQubo.from_dict(n=4, quadratic={(0,1):-1,(1,2):-1,(2,3):-1,(0,3):-1})
result = QAOASolver(qubo, p=2, seed=0).solve()
print(result.solution, result.cost)
