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 more operations 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 the control sequence based on the characteristics.
