qca-compiler

Compile QCA circuit specifications into Qiskit circuits that use only the native gate set {Rz, Rx, CZ}.

Built on the gate algebra established in QCA as a Native Quantum Platform:

• H = Rz(pi/2) . Rx(pi/2) . Rz(pi/2) -- 3 native gates
• S = Rz(pi/2) -- 1 native gate
• T = Rz(pi/4) -- 1 native gate
• CNOT = (I tensor H) . CZ . (I tensor H) -- 7 native gates

Install

pip install qca-compiler

CLI usage

qca-compile examples/bell.json -o bell.qasm --estimate

Input JSON format:

{ "n_qubits": 2, "gates": [ {"name": "H", "qubits": [0]}, {"name": "CNOT", "qubits": [0, 1]} ] }

Supported gates: H, S, T, X, Y, Z, CNOT, CZ, Rz(theta), Rx(theta).

Python API

from qca_compiler import parse, map_to_native, emit_qiskit, estimate

circ = parse("examples/bell.json") native = map_to_native(circ) qc = emit_qiskit(native) est = estimate(native)

Resource estimate

The estimate function reports:

• Native 1q and 2q gate counts
• Estimated circuit depth
• Predicted hardware fidelity based on IBM Eagle r3 error rates
