An international team of researchers (USA -research organization, UT Austin, UMass Amherst, Canada) has demonstrated an emergent dynamical symmetry-protected topological phase using an array of 10 trapped-ion of yitterbium as quantum processor. Each ion is individually held and controlled by electric fields produced by an ion trap and can be manipulated or measured using laser pulses. This phase showed edge qubits that are dynamically protected from control errors, crosstalk, and stray fields. The edge protection relies purely on emergent dynamical symmetries that are stable to generic coherent perturbations. The work paves the way for implementation of more complex dynamical topological orders that would enable error-resilient manipulation of quantum information…read more. TECHNICAL ARTICLEÂ
