PulseBackendConfiguration.describe¶

PulseBackendConfiguration.describe(channel)[source]¶

Return a basic description of the channel dependency. Derived channels are given weights which describe how their frames are linked to other frames. For instance, the backend could be configured with this setting:

u_channel_lo = [
    [UchannelLO(q=0, scale=1. + 0.j)],
    [UchannelLO(q=0, scale=-1. + 0.j), UchannelLO(q=1, scale=1. + 0.j)]
]

Then, this method can be used as follows:

backend.configuration().describe(ControlChannel(1))
>>> {DriveChannel(0): -1, DriveChannel(1): 1}

Parameters: channel (ControlChannel) – The derived channel to describe.
Raises: BackendConfigurationError – If channel is not a ControlChannel.
Return type: Dict[DriveChannel, complex]
Returns: Control channel derivations.
