Quandela
^^^^^^^^

`Quandela Cloud <https://cloud.quandela.com/>`_ provides access to physical and emulated quantum processing units.
It is Perceval's historical provider and offers all the capabilities that Perceval has.

QuandelaCommunicationLayer
==========================

.. autoclass:: perceval.providers.quandela.quandela_communication_layer.QuandelaCommunicationLayer

RemoteConfig
============

.. note::
   :ref:`Execution` serialization does not store credentials.
   To be able to deserialize an execution made through a Quandela computer,
   the :class:`RemoteConfig` needs to be configured.

>>> config = pcvl.RemoteConfig()
>>> config.set_token("your-personal-access-token")
>>> config.set_proxies({"https": "your-proxy"})  # Shared among all provider configs
>>> config.save()

After configuration, the token and provider name may be omitted from the communication layer:

>>> communication_layer = pcvl.QuandelaCommunicationLayer(
...     name=PLATFORM_NAME,
... )

.. note::
   Do not persist authentication tokens on shared or public computers. Using an environment variable or the in-memory
   configuration cache avoids writing the token to disk.

   This class is about the legacy workflow for providers.
   It should not be used, and is kept here only for backward compatibility
