There is no additional cost to use the Q-CTRL performance management strategy with the IBM Quantum Pay-As-You-Go plan.
Currently, this option is only available on devices accessible through the IBM Quantum Pay-As-You-Go plan. If you have access to a premium device and would like to deploy this technology, please contact us.
Q-CTRL evaluates a wide range of algorithmic benchmarks and reports quantitative metrics appropriate for each. Hardware validations show enhanced algorithmic success when a “correct” answer is known ahead of time, improved similarity of hybrid quantum algorithmic cost landscapes to the ideal, and enhancements to measured quantum volume. Q-CTRL’s performance management technology works with any algorithm possessing any structure of outputs, unlike other post processing techniques which work only in very limited circumstances.
Full details are available from our peer-reviewed technical publication. You can try running benchmark algorithms on your own by downloading our demo notebook.
Q-CTRL has developed an array of interoperable techniques which reduce errors from the gate level to the compiler level. This includes a high-performance depth-reducing compiler, error-aware layout selector, crosstalk-eliminating compiler, autonomous quantum gate/machine-language optimizer, and efficient measurement-error mitigation.
Full details are available in our peer-reviewed technical manuscript.
Q-CTRL’s deterministic error suppression works with any techniques executed above the compiler level. Combine easily with PEC, and other post-processing techniques. Discover the relationship between error suppression and error mitigation techniques in our Learning Center.

* Q‒CTRL deterministic error suppression technology reduces experimental shots to achieve a target confidence level by improving signal‒to‒noise levels and eliminates the need for sampling overhead required in error mitigation. Execution cost per QPU runtime second is identical with and without Q‒CTRL performance management selected.
