arvak-lite

Qiskit Ecosystem

Lightweight quantum circuit compiler wrapping Arvak. Takes circuits from any major framework, compiles them, and returns the same type.

from arvak_lite import transpile

compiled = transpile(circuit)

Also registers as a Qiskit transpiler plugin:

from qiskit.compiler import transpile

compiled = transpile(circuit, optimization_method="arvak")

Installation

pip install arvak-lite

With framework extras:

pip install arvak-lite[qiskit]      # Qiskit + transpiler plugin
pip install arvak-lite[cirq]        # Cirq
pip install arvak-lite[pennylane]   # PennyLane
pip install arvak-lite[pulser]      # Pulser (Pasqal)
pip install arvak-lite[qrisp]       # Qrisp
pip install arvak-lite[qbraid]      # qBraid multi-backend
pip install arvak-lite[all]         # Everything

Usage

Any framework

from arvak_lite import transpile

compiled = transpile(circuit)  # Qiskit in → Qiskit out, Cirq in → Cirq out, etc.

Qiskit transpiler plugin

Once installed, arvak is available as a named plugin in Qiskit's transpile():

from qiskit.compiler import transpile

# Use Arvak for optimization
compiled = transpile(circuit, optimization_method="arvak")

# Use Arvak for routing
compiled = transpile(circuit, coupling_map=coupling, routing_method="arvak")

# Or via pass manager
from qiskit.transpiler.preset_passmanagers import generate_preset_pass_manager
pm = generate_preset_pass_manager(optimization_level=3, optimization_method="arvak")
compiled = pm.run(circuit)

With metrics

compiled, metrics = transpile(circuit, return_metrics=True)
print(f"{metrics['time_ms']:.2f}ms, {metrics['gate_count']} gates")

Parameters

transpile(
    circuit,                          # Any supported circuit type
    optimization_level=3,             # 0=parse, 1=basic, 2=standard, 3=aggressive
    coupling_map=[[0,1], [1,2]],      # Device connectivity (None = all-to-all)
    basis_gates=["cx", "rz", "sx"],   # Target gate set
    return_metrics=True,              # Return (circuit, metrics) tuple
)

How it works

arvak-lite is a thin Python wrapper (~12 KB). The actual compilation happens in Arvak, a Rust-native compiler exposed via PyO3. The full compiler fits in a ~600 KB wheel — no LLVM, no JVM, no heavy runtime. The speed comes from Rust, not from skipping optimization passes.

  1. Detect the input framework from the circuit's type
  2. Convert to arvak.Circuit
  3. Compile in Rust (gate decomposition, routing, optimization)
  4. Convert back to the original framework type
