Abstract

See full text

A quantum computing system comprises a classical computing entity, a controller, and a quantum processor. The controller is configured to control operation of the quantum processor and communicate with the computing entity. The controller causes performance of syndrome circuit segments to generate syndromes of logical qubits. The syndrome circuit segment is performed at least partially by causing performance of a sequence of transportation operations and at-least-two-physical-qubits interactions. Each transportation operation of the sequence causes physical transport of at least one of a respective data qubit of the logical qubit or a respective ancilla qubit into a respective interaction zone defined by the quantum processor. A respective at-least-two-physical-qubits interaction is performed within the respective interaction zone. Using the syndrome, at least one quantum error correction is determined; and the controller causes a classical memory to be updated based on the syndrome and/or the quantum error correction.
