Workers

A worker implements atomic functionalities that will not be broken further by the controller. Tierkreis workers come in three flavors:

• Builtin workers, provided by Tierkreis itself

• User defined workers, by using the @worker.task() annotation or writing external ones

• Prepackaged workers from the Tierkreis developers

• Complex types in Tierkreis Python workers
  • JSON style types
  • Struct using NamedTuple
  • bytes
  • DictConvertible and ListConvertible
  • Pydantic BaseModels
  • Special Python types
• Custom serializers
• External Workers
  • IDL
  • Parsing Inputs and Outputs
• Hello world worker
  • Worker code
  • Generating stubs
  • Graph creation
  • Execution
• Prepackaged workers
  • Qiskit Aer worker
  • IBMQ Worker
  • Nexus worker
  • Pytket worker
  • Quantinuum Backend Worker
  • Qulacs worker

Prepackaged workers

The following outlines the functionality of the prepackaged workers. Currently the following workers are provided as separate packages on pypi:

• IBMQ

• Qiskit Aer

• Pytket

• Quantinuum Nexus

• Quantinuum Backend

Qiskit Aer

Compile and run quantum circuits locally with Qiskit Aer. More detailed docs here.

IBMQ

Compile and run quantum circuits locally with IBMQ. More detailed docs here.

Pytket

The pytket compiler suite to optimize circuits. The worker only contains a subset of common operations. For a custom compilation pipeline it is advised to build your own worker.

More detailed docs here.

Installation

pip install tkr-pytket-worker

will install an executable Python script tkr_pytket_worker into your virtual environment.

Example

See the example hamiltonian_graph.py.

Quantinuum Nexus

Interface to the Quantinuum Nexus platform. More detailed docs here.

Quantinuum Backend

Compile and run quantum circuits locally with Quantinuum backends. More detailed docs here.

Qulacs

Compile and run quantum circuits locally with Qulacs. More detailed docs here.
