There is provided a method for performing operations in a solid-state qubit processor. A provided (S100) logical qubit, comprising a plurality of data qubits, is extended (S102) and split (S104) to create two or more entangled portions. A first portion is shuttled (S106) in the qubit processor, separating it from a second portion, which may remain in place. During this shuttling process, faults may have occurred, which may have damaged or corrupted the first portion. Accordingly, a likelihood of fault is determined (S108), based upon a measurement operation. Based upon the likelihood of fault, the first portion or the second portion is selected (S110). In some examples, when selecting the first portion, the logical qubit is shuttled, and when selecting the second portion, the shuttling process is reversed and any potential damage or corruption to the first portion is reverted, with the logical qubit returned to its initial state. In this way, the method may provide a "logically reversible" shuttling operation.
