class loom.eka.channel.Channel(*args, **kwargs)

Bases: object

Identifies information channels connecting the Circuit elements: examples are classical or quantum bit channels

Parameter

type: ChannelType

The type of the channel: QUANTUM or CLASSICAL, default is QUANTUM

label: str

The label of the channel, allowing it to be grouped in a user friendly way, E.g. can be “red”, “ancilla_qubit” or “my_favourite_qubit”

id: str

The unique identifier of the channel

id: str = FieldInfo(annotation=str, required=False, default_factory=<lambda>)

is_classical()

Check if the channel is a classical channel. :returns: True if the channel is a classical channel, False otherwise. :rtype: bool

is_quantum()

Check if the channel is a quantum channel.

Returns:

True if the channel is a quantum channel, False otherwise.

Return type:

bool

label: Optional[str] = None

classmethod set_default_label(v, info)

Set the default label based on the type of the channel, according to the following scheme: ChannelType.QUANTUM: “data_qubit” ChannelType.CLASSICAL: “classical_bit”

Return type:

str

type: ChannelType = 'quantum'

class loom.eka.channel.ChannelType(*values)

Bases: str, Enum

The type of the channel: QUANTUM or CLASSICAL More types should be added when we feel the need for it

CLASSICAL = 'classical'

QUANTUM = 'quantum'

loom.eka.channel.create_default_label(channel_type)

Creates a default label for the channel.

Parameters:

channel_type (ChannelType) – The type of the channel: QUANTUM or CLASSICAL

Returns:

The default label for the channel

Return type:

str
