abrax 0.2.1

A Quantum Circuit DSL

abraxas

A tiny DSL to compile to qiskit circuits. The goal is to speed up the time it takes to write small stupid circuits. Anything beyond a certain complexity should be written in qiskit directly.

Install

While not specified here you will need Qiskit since Abraxas takes in an initialized QuantumCircuit object to write to.

pip install abrax

Examples

Fairly Complex

from abrax import A
from qiskit import QuantumCircuit

qc = QuantumCircuit(5)
qc = A("""
  - H CX(4) RX(10)
  - H -    -
  - H -    CX(4)
  - H X    RY(55)
  - H -    -
  """, qc
)

# Should be equivalent to
from qiskit import QuantumCircuit

qc = QuantumCircuit(5)
qc.h([0, 1, 2, 3, 4])
qc.cx(0, 4)
qc.x(3)
qc.rx(10, 0)
qc.cx(2, 4)
qc.ry(55, 3)
qc.measure_all()

Simple

from abrax import A
from qiskit import QuantumCircuit

qc = QuantumCircuit(2)
# This will apply H, H to 0-qubit & 1-qubit
# Then a CX on 0-qubit (as target) with 1-qubit as control
qc = A("""
  - H CX(1)
  - H -
  """, qc
)

Syntax

• Note All lines must start with a - or |> (continuation operator NotImplemented yet)
• Everything else is a comment
• Case insensitive

Passing Config

qc = A("""
- H CX(1)
- H -
""", qc,
config={
  "measure": False,
})

Key	Type (Default)	Description
measure	bool (True)	Whether to measure all qubits at the end of the circuit
