True-Q™ provides methods to calibrate and optimize the performance of quantum devices. This includes diagnostic tools, which generate quantum circuits that measure noise properties of your device, and runtime solutions, which tailor and reduce noise profiles.
To install True-Q™, navigate to the folder containing
setup.py and run:
pip install .
which will install it as a site-package in your current Python environment. Note that
you must have your
qb-token.json located in the same directory as
setup.py in order
to perform the installation successfully.
If you want to be able to run tests, view documentation locally, or edit the Python source code, then it is easiest to install True-Q™ in the editable mode using:
pip install -e .
To use True-Q™, you must have a 64-bit version of Python 3.6 or above, and you need to meet the following OS-specific requirements:
libstdc++ >= 8.2.1
libSystem.B >= 1252.250.1and
libc++ >= 400.9.4
Microsoft Visual C++ 2015-2019 Redistributable (x64) >= 14.27.29112(download it here)
A full list of required Python packages can be found in the
True-Q™ is capable of interfacing with other Python quantum computing packages, such as Cirq, pyQuil, and Qiskit. This functionality is optional and becomes available automatically whenever any of these packages are installed on your machine.
If you installed True-Q™ using
pip install . command, you can update it via:
pip install . -U
If you installed True-Q™ in the develop or editable mode, you can update your local copy using:
python setup.py update
Installation without Internet¶
If you are using a sandboxed version of True-Q™ and you want to install it on a
computer without Internet access, you can do so as follows. First, ensure that you are
working on a different computer with Internet access. If you do not have a local copy of
True-Q™ (i.e. you only have
setup.py), you can obtain all of
the required files by running:
python setup.py get_all
Once everything has been downloaded, you can copy this folder to your target machine and run the following command to perform a local (offline) installation:
python setup.py local_install
Note that your target machine must also have all of the required Python packages
requirements.txt, otherwise True-Q™ will not function
You can view True-Q™ documentation and examples online at https://trueq.quantumbenchmark.com/.
If you have a local copy of True-Q™, you can open
documentation.html in your
browser to view it.
Alternatively, documentation can be built manually from source, which is located in the
docs folder. If you are building from source, ensure that you have all of the required
Python packages installed by doing:
pip install -r requirements_optional.txt pip install -r docs/requirements.txt
To manually build the documentation, execute the following commands:
cd docs && make html && cd ..
If successful, the compiled documentation will appear in the
which could be accessed via the
documentation.html shortcut with your browser.
Running tests requires the
pytest package, which can be installed via:
pip install pytest>=4.4
Once installed, navigate to the folder containing
setup.py and run:
to run tests from the
tests folder using the installed version of True-Q™. You
can also run tests against the local copy of True-Q™, rather than the installed
version, by running:
python -m pytest
Note that many of these tests involve quantum simulation, and therefore it might take a minute or two to run all of them.
A troubleshooting script is included that checks True-Q™, its dependencies, and
the connection to the server and produces a log file of the results. To run the script
from the command line, navigate to the
trueq folder and then run:
from the command line. Make sure to use the same version of Python that you will use
with True-Q™ since you may have multiple copies of Python installed, especially if
you use Anaconda. This will generate a file called
If you are having trouble running this script via command line, you can also execute it
through Jupyter (IPython) Notebook. First, copy the full file path of
located in your
trueq folder, paste it into the code below, and run it. (To get the
full path on Windows, hold shift and right click on
troubleshoot.py in Explorer and
select “Copy as path”. On macOS, right click on
troubleshoot.py in Finder, hold down
Alt/Option, and select “Copy troubleshoot.py as Pathname”. On Linux,
right click on
troubleshoot.py in Files and select “Copy”.)
import os import subprocess import sys full_path = "/your/trueq/path/troubleshoot.py" log_file = os.path.join(os.path.dirname(full_path), "troubleshoot.log") subprocess.call([sys.executable, full_path, "--filename", log_file]) with open(log_file, "r") as f: print(f.read())
