a The system consists of the two-qubit ancillary register (orange ions) and the three-qubit system register. The latter is further partitioned into the one-qubit subsystem A (a red ion) and its complement \(\bar{A}\) (blue ions). b The H1-1 quantum computer operates by manipulating the ions representing the qubits. Each quantum operation (initialization, gate application, measurement) is performed using lasers after the target ions are transported to one of the isolated interaction zones. In the experiments we use five out of the 20 qubits available, and apply up to 328 two-qubit gates.
