A quantum error correction method for a quantum computing system comprises: receiving syndrome data (e.g. surface code stabilizer measurements) identifying defects of quantum devices in the system, and setting defect states of nodes 202 in a decoding hypergraph accordingly; identifying elements of the hypergraph associated with a logical observable of a quantum error correction code (e.g. logical X or Z); determining decoding windows associated with logical observable subsets, e.g. l1, of the logical observable; independently decoding the decoding windows to determine partial corrections; combining the partial corrections to determine an aggregate correction for an error state of quantum devices in the quantum computing system. Partial corrections may relate to parity, whereas the aggregate correction may indicate whether the logical observable is affected by the error state. Each decoding window comprises all hypergraph elements within a predetermined distance associated with a code distance of the quantum error correction code, while two adjacent windows are decoded in parallel. Determining decoding windows may comprise partitioning the logical observable into subsets, the subsets being non overlapping and associated to contiguous elements of the hypergraph. Unlike the sliding and parallel decoding window techniques, no information needs to be passed between decoding windows as each window is decoded independently of the others thereby reducing latency. figure 5d

The disclosure is directed to a quantum processor system. The system includes a transmission line, a resonator, a qubit coupled to the resonator, and a switching device that couples and decouples the resonator to the transmission line. The resonator stores a range of energies based on a frequency that characterizes the resonator. When a quantum state of the qubit is equivalent to an excited state and the qubit is tuned in accordance with the frequency, energy is transferred from the qubit to the resonator, which stores the energy. The quantum state of the qubit is transitioned to a ground state. When the switching device is closed, the resonator is coupled to the transmission line such that the energy is transferred to the transmission line. When the switching device is opened, the resonator is decoupled from the transmission line.
