class qns.entity.qchannel.losschannel.QubitLossChannel(name: str | None = None, node_list: List[QNode] = [], bandwidth: int = 0, delay: float | DelayModel = 0, p_init: float = 0, attenuation_rate: float = 0, max_buffer_size: int = 0, length: float = 0, decoherence_rate: float | None = 0, transfer_error_model_args: dict = {})[source]

Bases: QuantumChannel

QubitLossChannel is the channel that can loss qubits.

The loss rate is: 1-(1-p_init)*10^{- attenuation_rate * length / 10}

Bases: Entity

QuantumChannel is the channel for transmitting qubit

install(simulator: Simulator) → None[source]

install is called before simulator runs to initialize or set initial events

Parameters:: simulator (Simulator) – the simulator

send(qubit: QuantumModel, next_hop: QNode)[source]

Send a qubit to the next_hop

Parameters:

qubit (QuantumModel) – the transmitting qubit
next_hop (QNode) – the next hop QNode

Raises:

NextHopNotConnectionException – the next_hop is not connected to this channel

Bases: Event

The event for a QNode to receive a classic packet

invoke() → None[source]: Invoke the event, should be implemented
