Abstract: A quantum computing system and methods for performing fusion based quantum computing on encoded qubits. A fusion controller sequentially performs a series of fusion measurements on respective photonic quantum modes of first and second encoded qubits to obtain a respective series of classical measurement results. For respective fusion measurements of the series of fusion measurements, a basis for performing the respective fusion measurement is selected based on classical measurement results of previous fusion measurements. An encoded fusion measurement result is determined based on the classical measurement results, and the encoded fusion measurement result is stored in a memory medium.

Abstract: Circuits are provided that create entanglement among qubits having Gottesman-Kitaev-Preskill (GKP) encoding using photonic systems and structures. For example, networks of beam splitters and homodyne measurement circuits can be used to perform projective entangling measurements on GKP qubits from different quantum systems. In some embodiments. GKP qubits can be used to implement quantum computations using fusion-based quantum computing or other fault-tolerant quantum computing approaches.

Abstract: Fusion-based quantum computations can be implemented using a network of interleaving modules. Each interleaving module can receive or produce resource states consisting of entangled physical qubits and can include a set of reconfigurable fusion circuits that can be controlled to perform either fusion operations or single qubit measurements on pairs of qubits from different resource states, routing paths connected to the reconfigurable fusion circuits, and delay lines and routing switches that operate to select routing paths for qubits of the resource states, thereby implementing a desired combination of fusion operations and single qubit measurements. The routing paths can include local routing paths that couple to reconfigurable fusion circuits in the same interleaving module and network routing paths that couple a routing switch in one interleaving module to a reconfigurable fusion circuit in a different interleaving module within the network.
