Alice And Bob

AliceBobBackendPreferences

Backend preferences specific to Alice&Bob for quantum computing tasks. This class includes configuration options for setting up a backend using Alice&Bob’s quantum hardware. It extends the base BackendPreferences class and provides additional parameters required for working with Alice&Bob’s cat qubits, including settings for photon dissipation rates, repetition code distance, and the average number of photons. Attributes:

Name	Type	Description
`parameters`	`dict[str, Any]`
`backend_service_provider`	`ProviderTypeVendor.ALICE_BOB`	The service provider for the backend, which is Alice&Bob.
`distance`	`Optional[int]`	The number of times information is duplicated in the repetition code. - Tooltip: Phase-flip probability decreases exponentially with this parameter, bit-flip probability increases linearly. - Supported Values: 3 to 300, though practical values are usually lower than 30. - Default: None.
`kappa_1`	`Optional[float]`	The rate at which the cat qubit loses one photon, creating a bit-flip. - Tooltip: Lower values mean lower error rates. - Supported Values: 10 to 10^5. Current hardware is at ~10^3. - Default: None.
`kappa_2`	`Optional[float]`	The rate at which the cat qubit is stabilized using two-photon dissipation. - Tooltip: Higher values mean lower error rates. - Supported Values: 100 to 10^9. Current hardware is at ~10^5. - Default: None.
`average_nb_photons`	`Optional[float]`	The average number of photons. - Tooltip: Bit-flip probability decreases exponentially with this parameter, phase-flip probability increases linearly. - Supported Values: 4 to 10^5, though practical values are usually lower than 30. - Default: None.
`api_key`	`str`	The API key required to access Alice&Bob’s quantum hardware. - Required: Yes.
