  • Fast control of quantum systems is essential to exploit their properties for information processing before they are lost to decoherence. Here the authors demonstrate the use of quasi instantaneous changes to the trapping potential of a trapped-ion to create highly-excited quantum coherent states.

  • Time-varying Hamiltonians can be reconstructed experimentally if the variation takes place in a single basis, but more general cases are complicated. Here, the authors present an approach to estimate the general time-dependent Hamiltonian of a single spin-qubit and apply it to a trapped-ion transported through a static laser beam.

  • A single logical qubit is encoded, manipulated and read out using a superposition of displaced squeezed states of the harmonic motion of a trapped calcium ion.
