Abstract: A method and a device for correcting quantum state information are disclosed. A decoder receives information identifying syndrome values for a plurality of entangled qubit states represented by a graph state with a respective edge of the graph state corresponding to a respective qubit state of the plurality of entangled qubit states. The decoder repeats identifying one or more clusters of qubit states and/or syndrome states in the graph state until all of the one or more identified clusters are determined to be valid while increasing a size of a respective cluster each time the identifying operation is performed. The decoder reconstructs one or more qubit states and/or syndrome states for respective clusters; and stores information identifying the one or more reconstructed qubit states and/or syndrome states.

Abstract: A method includes receiving a plurality of quantum systems, wherein each quantum system of the plurality of quantum system includes a plurality of quantum sub-systems in an entangled state, and wherein respective quantum systems of the plurality of quantum systems are independent quantum systems that are not entangled with one another. The method further includes performing a plurality of joint measurements on different quantum sub-systems from respective ones of the plurality of quantum systems, wherein the joint measurements generate joint measurement outcome data and determining, by a decoder, a plurality of syndrome graph values based on the joint measurement outcome data.

Abstract: A device includes a plurality of first switches. Each first switch includes a set of two or more first channels. Each first switch is configured to shift photons in the set of first channels by zero or more channels, based on first configuration information provided to the first switch. The device further includes a plurality of second switches. Each second switch includes a corresponding set of two or more second channels. The plurality of second switches is coupled to two or more output channels. Each second switch is coupled, by the set of second channels, to outputs of two or more first switches. Each second switch is configured to shift photons in the set of second channels by zero or more channels, based on second configuration information provided to the second switch so that photons are provided to respective output channels of the two or more output channels.

Abstract: Entanglement among qubits can be generated using “rasterized” and interleaving techniques. A circuit can include a resource state generator that generates one resource state per clock cycle, with each resource state having a number of entangled qubits. The circuit can also include circuits and delay lines to perform entangling measurement operations on qubits of resource states generated by the same resource state generator in different clock cycles. With appropriate selection of delay lines, a single resource state generator can generate all of the resource states needed to generate a large entanglement structure. Hybrid techniques can also be used, where the number of resource state circuits is greater than one but less than the number of resource states needed to generate the entanglement structure.
