Abstract

We demonstrate experimentally a robust quantum memory using a magnetic-field-independent hyperfine transition in Be+9 atomic ion qubits at a magnetic field B 0.01194T. We observe that the single physical qubit memory coherence time is greater than 10 s, an improvement of approximately 5 orders of magnitude from previous experiments with Be+9. We also observe long coherence times of decoherence-free subspace logical qubits comprising two entangled physical qubits and discuss the merits of each type of qubit.
