Qiskit IBM Quantum Provider for accessing the quantum devices and simulators at IBM

Qiskit IBM Quantum Provider

Qiskit is an open-source SDK for working with quantum computers at the level of circuits, algorithms, and application modules.

This project contains a provider that allows accessing the IBM Quantum systems and simulators.

Migrating from qiskit-ibmq-provider

If you are familiar with the qiskit-ibmq-provider repository, check out the migration guide.

Installation

You can install the provider using pip:

pip install qiskit-ibm-provider

Provider Setup

1. Create an IBM Quantum account or log in to your existing account by visiting the IBM Quantum login page.

2. Copy (and/or optionally regenerate) your API token from your IBM Quantum account page.

3. Take your token from step 2, here called MY_API_TOKEN, and save it by calling IBMProvider.save_account():

   from qiskit_ibm_provider import IBMProvider
   IBMProvider.save_account(token='MY_API_TOKEN')
   

   The command above stores your credentials locally in a configuration file called qiskit-ibm.json. By default, this file is located in $HOME/.qiskit, where $HOME is your home directory. Once saved you can then instantiate the provider like below and access the backends:

   from qiskit_ibm_provider import IBMProvider
   provider = IBMProvider()
   
   # display current supported backends
   print(provider.backends())
   
   # get IBM's simulator backend
   simulator_backend = provider.get_backend('ibmq_qasm_simulator')
   

Load Account from Environment Variables

Alternatively, the IBM Provider can discover credentials from environment variables:

export QISKIT_IBM_TOKEN='MY_API_TOKEN'

Then instantiate the provider without any arguments and access the backends:

from qiskit_ibm_provider import IBMProvider
provider = IBMProvider()

Enable Account for Current Session

As another alternative, you can also enable an account just for the current session by instantiating the provider with the token.

from qiskit_ibm_provider import IBMProvider
provider = IBMProvider(token='MY_API_TOKEN')
