Embodiment Construction

[0076] The present disclosure provides a quantum computing system in which a user, such as an operator or researcher of a commercial quantum computer, can interact with an intuitive user interface to determine and perform a process to stabilize control over a qubit change. In particular, the user interface helps the user identify the appropriate controls to execute on the quantum computing system. The user interface interacts with the cloud-based computing system to execute algorithms for characterization of quantum computing hardware, performance evaluation of various control methods given the characterization, and optimization of control given the characterization. As a result, the cloud system returns a control sequence that reduces errors due to flaws in the control or control hardware in the quantum computer and returns performance metrics such as error probability. These algorithms are so computationally intensive that they are impractical to run on a local computer. A...

Abstract

This disclosure relates to quantum computing systems including a quantum processor that implements one or more operations on multiple qubits and a distributed data processing system programmed to perform calculations to determine control sequences that, when applied to the quantum processor, reduces decoherence, decoherence-induced errors, and control-imperfection-induced errors on the one or moreoperations on the multiple qubits. A user interface device remote from the distributed data processing system receives from a user of the quantum processor characteristics of the quantum processor including operational constraints and / or desired performance, and sends the characteristics to the data processing system to cause the data processing system to perform the calculations to determine thecontrol sequence based on the characteristics.
