qprof_qiskit being a Python module, it is installable with pip.

git clone https://gitlab.com/qcomputing/qprof/qprof_qiskit.git
pip install qprof_qiskit/

Usage

Profiling

Profiling is performed with the qprof.profile function.

The qprof.profile function needs a quantum routine implemented with one of the supported frameworks along with the “base” gate times provided as a dictionary.

Example of profiling:

# Import the qprof tools
from qprof import profile

# Import the framework tools to generate a quantum routine
from qiskit.aqua.algorithms import Grover
from qiskit.aqua.components.oracles import LogicalExpressionOracle


# Generate the routine to benchmark.
input_3sat = """
c example DIMACS-CNF 3-SAT
p cnf 3 5
-1 -2 -3 0
1 -2 3 0
1 2 -3 0
1 -2 -3 0
-1 2 3 0
"""

oracle = LogicalExpressionOracle(input_3sat)
grover = Grover(oracle)
circuit = grover.construct_circuit()

# Hard-coded gate times retrieved by hand
gate_times = {"U1": 0, "U2": 89, "U3": 178, "CX": 930, "BARRIER": 0}

# Profile the resulting quantum circuit and use the "gprof" exporter
qprof_out = profile(circuit, gate_times, "gprof")

# Print to stdout the analysis report
print(qprof_out)

Profile the code

Let save the code of the previous section in a file profile.py.

You can generate the following graph with the command
