qcal

qcal is software for quantum calibration, characterization, and benchmarking.

Installation

Install from PyPI:

pip install quantum-calibration

Getting started

Here's an example of creating a Bell state preparation circuit in qcal:

import qcal as qc

circuit = qc.Circuit([
  qc.Cycle({qc.H(0)}),
  qc.Cycle({qc.CNOT((0, 1))})
])
circuit.measure()
circuit.draw()
