QPU-Specific Physical Properties

The attached documents provide physical properties particular to the QPUs 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.

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

Solvers (not all solvers may be online in Leap):

In addition to the above 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.

  • 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

  • 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?

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

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

  • 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!
