API

:eyes: Please check the main doc. The method signature is the same but:

• As expected, the engine parameter is omitted here.
• All algorithms need a background job, so a jobId is returned.
• About the options:
  • custom (object): Mandatory here, it should be a logged qiskit-cloud instance.
  • backend (string): Name of the backend to use. (default: simulator)
  • shots (number): Number of times to run the circuit. (default: 1)
  • maxCredits (number): Max number of the credits to run this job. The task will be cancelled if it needs more.
