Characterizing crosstalk of a quantum computing system based on sparse data collection

A computer-implemented method, comprising:

• selecting, by a system operatively coupled to a processor, a set of pairs of quantum gates from all pairs of quantum gates of a quantum device, wherein each pair of quantum gates in the set has exactly one other quantum gate intervening between the quantum gates of the pair;
• and
• packing, by the system, the pairs of quantum gates of the set into bins;
• and
• characterizing, by the system, crosstalk of the quantum device based on the bins into which the pairs of quantum gates are packed.

A computer program product facilitating a process to characterize crosstalk of a quantum computing system based on sparse data collection, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• select, by the processor, a set of pairs of quantum gates from all pairs of quantum gates of a quantum device, wherein each pair of quantum gates in the set has exactly one other quantum gate intervening between the quantum gates of the pair;
• and
• pack, by the processor, the pairs of quantum gates of the set into bins;
• and
• characterize, by the processor, the crosstalk of the quantum device based on the bins into which the pairs of quantum gates are packed.

A system, comprising:

• a memory that stores computer executable components;
• and
• a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise:
• an identification component that identifies at least one bin of quantum gates, from a group of bins of quantum gates of a quantum device, that generates a defined level of crosstalk, wherein respective bins of the group of bins comprise different subsets of pairs of quantum gates of a set of pairs of quantum gates selected from all pairs of quantum gates of the quantum device, and wherein each pair of quantum gates in the set has exactly one other quantum gate intervening between the quantum gates of the pair;
• and
• an assessment component that characterizes crosstalk of the quantum device based on the at least one bin of quantum gates.
