Installation instructions

Install first the package dependencies with the following commands.

We recommend to start with a fresh virtual environment to avoid dependencies conflicts with previously installed packages.

   $ python -m venv ./env
   source activate ./env/bin/activate

The qibo-client-backends package can be installed through pip:

   pip install qibo-cloud-backends

Quickstart

Once installed, the plugin allows for setting and using the new backends in Qibo.

The following two examples show how to submit a job on the TII cluster and the IBM servers. Remember to replace "your token" string with your actual valid token received after registration. Alternatively, you can register your token under the environment variables QIBO_CLIENT_TOKEN for qibo-client and IBMQ_TOKEN for qiskit-client.

Prepare a QFT circuit to be submitted to the servers:

   import qibo

   circuit = qibo.models.QFT(5)
   circuit.add(qibo.gates.M(0, 2, 4))

Then, to simulate the circuit on the TII cluster through the sim platform:

   qibo.set_backend("qibo-cloud-backends", client="qibo-client", token="your_token", platform="sim")
   result = circuit()
   print(result.frequencies())

or, in order to run on one of the chips hosted in ibm-q, e.g. ibm_osaka:

   qibo.set_backend("qibo-cloud-backends", client="qiskit-client", token="your_token", platform="ibm_osaka")
   result = circuit()
   print(result.frequencies())
