QPU-Specific Physical Properties

The Physical Properties documents on the QPU-Specific Characteristics page describe the physical properties particular to the QPUs that are available through Leap. For each QPU, the associated document includes a summary of its physical properties, an image of the working graph, and plotted data showing the anneal schedule and other details.

Note: The values provided in these documents are the physical properties of a calibrated QPU. They are not QPU specifications.

In addition to the aforementioned list of physical properties, each QPU has a number of other properties defined in software that are accessible via the Solver API. For a global list of the solver properties for a QPU, and for a list of the permitted user parameters for each type of solver, see Solver Properties and Parameters. To retrieve the solver properties for a particular QPU, see the Ocean documentation for the syntax and examples.

  • I was able to get a list of qubits and couplers for each.
    I have attached them in text files to the original ticket above.
    I included DW_2000Q_6 for good measure.
    The filenames are:
    dw_2000q_2_1-qubits_and_couplers.txt
    dw_2000q_5-qubits_and_couplers.txt
    dw_2000q_6-qubits_and_couplers.txt

    They are in python dictionary format, so they can be copied into a script or read in.

    I hope this helps answer your question.
    Please reach out if you have any more questions!

  • Hello,
    Just wondering if you could give a little more information about your question.
    Are you asking for a list of working vs non-working qubits for one of the solvers that is offline (i.e. the working graph of DW_2000Q_2_1)?
    Or are you asking how to obtain the working graph of a given solver?

  • Where would I be able to find the chimera graph adjacency of devices that are currently offline?
    The PDFs include drawings of the adjacency, but it'd be useful to have that data in a way that could be parsed

  • I'm asking about offline solvers like DW_2000Q_2_1 and DW_2000Q_5.

    Yes, basically the `couplers` property of offline solvers.
