AB - Quantum error-correcting codes are many-body entangled states used to robustly store coherent quantum statesover long periods of time in the presence of noise. Practical implementations will require efficient entanglingprotocols that minimize the introduction of noise during encoding or readout. We propose an experiment thatuses only global operations to encode information to either the five-qubit repetition code or the five-qubit code ona two-dimensional ion Coulomb crystal architecture. We show we can prepare, read out, and acquire syndromeinformation for these two codes by using only six and ten global entangling pulses, respectively. We provide anerror analysis, estimating we can achieve a sixfold improvement in coherence time with as much as 1% noise inthe control parameters for each entangling operation.
