Abstract

Using a mixed-species ion chain, we demonstrate up to 50 sequential parity measurements between two beryllium ion qubits coupled to a co-trapped ancillary calcium ion. With feedback on the beryllium qubits conditioned on the ancilla readout we stabilize Bell states and parity subspaces. [1]
