Abstract
This application concerns methods and apparatus for performing a quantum algorithm of logical qubits. The quantum algorithm is performed on a quantum system of physical qubits. The method includes providing a quantum system comprising a plurality of physical qubits in a spatial arrangement. The number of physical qubits is larger than the number of logical qubits. The logical qubits are encoded into physical qubits. A physical qubit represents either the parity of two or more logical qubits or a single logical qubit. Constraint-fulfilling sets of physical qubits fulfil constraints and each constraint-fulfilling set comprises a number of physical qubits such that every logical qubit is represented by zero or an even number of physical qubits in that set. The method includes enabling quantum interactions between logical qubits by performing quantum interactions on physical qubits. Further, at least a portion of the physical qubits is measured to obtain a readout.
