netqasm.backend.qnodeos

Quantum node controller interface for simulators.

This module provides the QNodeController class which can be used by simulators as a base class for modeling the quantum node controller.

class netqasm.backend.qnodeos.QNodeController(name, instr_log_dir=None, flavour=None, **kwargs)

Bases: object

Class for representing a Quantum Node Controller in a simulation.

A QNodeController represents a physical quantum node controller that handles messages coming from the Host, lets the Executor execute subroutines, and sends results back to the Host.

Parameters

• name (str) –

• instr_log_dir (Optional[str]) –

• flavour (Optional[Flavour]) –

__init__(name, instr_log_dir=None, flavour=None, **kwargs)

QNodeController constructor.

Parameters

• name (str) – name used for logging purposes

• instr_log_dir (Optional[str]) – directory used to write log files to

• flavour (Optional[Flavour]) – which NetQASM flavour this quantum node controller should expect and be able to interpret
