NetSquid Forum

Release 0.9

Change to authenticated access for online documentation and pypi server

• Access to the online documentation and to the NetSquid python package server now requires valid user credentials for the NetSquid forum.
• Access to the package server must be explicitly granted by an administrator until the user license agreement has been finalised.

Major new features and improvements

Added a Network component

• The Network component holds and manages Nodes and the Connections between them.
• It supports automatic creation of Nodes and Connections.
• It supports connecting Nodes via Connections.

New protocol subclasses

• Added ServiceProtocol, an abstract subclass of NodeProtocol that defines an interface for specifying service requests and responses.
• Added DataNodeProtocol, an abstract subclass of NodeProtocol intended for processing incoming data on ports e.g. from connections. It replaces the DataProtocol, which has been been deprecated.

Quantum program arguments and concatenation

• Added a qubit_mapping parameter to a QuantumProgram constructor to allow concatenation of programs with different numbers of qubits or different qubit mappings.
• Keyword arguments can now be passed through to a quantum program calling the execute_program method of a quantum processor.

Improved documentation

• Changes to tutorial and getting started guide based on user feedback (alpha test).
• Added an example module for simulating repeater chains.
• Added an example module that simulates a link layer protocol.
• Added walkthrough guides for all examples.
• Added table of contents and learning goals to tutorial.

Minor features and improvements

• Forwarding the input of a port is only allowed to a sub-component, and forwarding the output of a port is only allowed to a super-component.
• Added a filter_by_type(self, value_type) to ConstraintMap, which will return a ConstrainedMapView which has everything that is not the given type filtered out.
• A ConstrainedMapView allows viewing the data of the ConstraintMap without changing it.
• The components.fibres module has been deprecated. The standard classical and quantum channels with the appropriate fibre models can be used instead.

New package version dependencies

• The required pyDynAA version is 0.3
• Set minimum Numpy dependency to version 1.16
• Set minimum SciPy dependency to version 1.3
• Set minimum Pandas depencency to version 0.25
