Connections - Quantum and classical channels

class netQuil.connections.QConnect(*args, transit_devices=[])

__init__(*args, transit_devices=[])

This is the base class for a quantum connection between multiple agents.

Parameters

• *args (agents) – list of agents to connect

• transit_devices (List<Devices>) – list of devices qubits travel through

__weakref__

list of weak references to the object (if defined)

get(agent)

Pops qubits off of the agent’s queue. Sends qubit through transit and target devices, simulating a quantum network. Return an array of the qubits that have been altered, as well as the time it took the qubit to travel through the network. Some qubits may be lost during transmission. If lost, their value will switch to negative, or, in the case of 0, be set to -inf

Parameters

agent (Agent) – agent receiving the qubits

Returns

list of qubits, time to pass through transit and target devices, and the source agent’s time

put(source, target, qubits, source_time)

Constructs full list of devices that each qubit must travel through. Sends the qubits through source devices. Places qubits and a list of transit and target devices on the queue. Queue is keyed on the target agent’s name.

Parameters

• source (String) – name of agent where the qubits being sent originated

• target (String) – name of agent receiving qubits

• qubits (Array) – array of numbers corresponding to qubits the source is sending

• source_time (Float) – time of source agent before sending qubits

Returns

time qubits took to pass through source devices

transit_devices = None

Create queue to keep track of multiple requests. Name of queue is name of target agent.

class netQuil.connections.CConnect(*args, length=0.0)

__init__(*args, length=0.0)

This is the base class for a classical connection between multiple agents.

Parameters

• *args (agents) – list of agents to connect

• length (Float) – distance between first and second agent

__weakref__

list of weak references to the object (if defined)

agents = None

Create queue to keep track of multiple requests. Name of queue is name of target agent.

get(agent)

Pops cbits off of the agent’s queue and adds travel delay

Parameters

agent (String) – name of the agent receiving the cbits

Returns

cbits from source and time they took to travel

put(target, cbits)

Places cbits on queue keyed on the target Agent’s name

Parameters

• target (String) – name of recipient of program

• cbits (Array) – array of numbers corresponding to cbits agent is sending

Returns

time for cbits to travel
