Summary of results

You must consider the following when deciding which QPU can be used for calculations:

• The number of qubits needed for the problem and the qubit limit of the device
• The speed of execution (processing time and the time in the queue)
• The minimum number of shots required for accurate results versus the shot limit of the device
• The quality of the results that’s expected based on the errors of the device
• The quadratic terms in the matrix (full versus sparse matrix) and the qubit’s interconnectivity
• The cost of execution that was evaluated based on the execution time or the number of shots
• The probabilistic versus exact result requirement to decide between measurements (shots) versus state vector results or a classical solver
• Gate-based versus quantum annealing (also known as gate-based simulator versus simulated annealer)
• The availability of the device (review the schedule when certain quantum devices are available...
