CQCExtractor¶

class CQCExtractor(name, provider, client, methods)[source]¶

Bases: qiskit.providers.ibmq.random.baserandomservice.BaseRandomService

Class for interfacing with a CQC remote extractor.

There are two extractor methods - Dodis (extractor 1) and Hayashi (extractor 2). These methods can be invoked synchronously or asynchronously. To invoke them synchronously:

random_bits = extractor.run(*cqc_parameters)

To invoke them asynchronously:

import numpy as np
extractor1_out = extractor.run_async_ext1(*ext1_parameters).block_until_ready()
extractor2_out = extractor.run_async_ext2(
    ext2_seed=extractor1_out, *ext2_parameters).block_until_ready()
random_bits = np.append(extractor1_out, extractor2_out)

Running them asynchronously takes more steps because extractor 2 uses the output of extractor 1 as its seed, so it must wait for extractor 1 to finish first.

BaseRandomService constructor.

Parameters

name (str) – Name of the extractor.
provider (AccountProvider) – IBM Quantum Experience account provider.
client (RandomClient) – Client used to communicate with the server.
methods (List) – Service methods.

Methods

`retrieve_job`	Retrieve a previously submitted job.
`run`	Process input data synchronously.
`run_async_ext1`	Run the first extractor asynchronously.
`run_async_ext2`	Run the second extractor asynchronously.
