abraxas

A tiny library to transpile quantum circuits. The goal is to speed up the time it takes to convert simple circuits across languages fast. Anything beyond a certain complexity should be written in the respective languages directly.

Qiskit • CudaQ • Pennylane • Cirq • TKet • Quil • Braket

Install

Qiskit has also been marked as a dependency since about a third of the functions use it anyway.

pip install abrax

Examples

toPennylane

from qiskit import QuantumCircuit, Parameter
from abrax import toPenny, toQasm
import pennylane as qml

qc = QuantumCircuit(3)
p = Parameter('x')
qc.h([0, 1, 2])
qc.cx(0, 2)
qc.rx(0, 0)
qc.cx(1, 2)
qc.ry(p, 2)

qasm = toQasm(qc)
dev = qml.device("default.qubit", wires=2)
circuit = toPenny(qasm, dev) # pennylane needs 'dev'
# print(qml.draw(circuit)())
# 0: ──H─╭X──RX(0.00)───────────────┤  Probs
# 1: ──H─│────────────╭X────────────┤  Probs
# 2: ──H─╰●──X────────╰●──RY(x)─────┤  Probs
