DESCRIPTION:Speaker: Jonathan Home\nhosted by  Julian Léonard\nAbstract: A
 bstract: The development of useful quantum computers will rely on the abil
 ity to suppress errors which occur both naturally and through the erroneou
 s application of gate operations. Error-correction typically comes with si
 gnificant resource overheads\, which motivates the search for implementati
 ons which can naturally provide error correction in a compact manner. One 
 approach is to use bosonic degrees of freedom to encode information redund
 antly\, allowing to perform feedback which suppresses errors. I will descr
 ibe two sets of experiments in which we perform operations and bosonic err
 or correction using mechanical oscillations of a single trapped ion. In th
 e first\, we demonstrate the entanglement and subsequent error-correction 
 of logical qubits encoded using superposed displaced squeezed states formi
 ng periodic structures in phase space. This “GKP” encoding is particul
 arly well suited to diffusive errors in the oscillator phase space. Then\,
  using a novel non-linear regime of control\, I will show how we realize n
 on-linear reservoir engineering to perform confinement of states into fini
 te-dimensional subspaces which have discrete rotational symmetry\, and whi
 ch protect from dephasing errors. Alongside coverage of the state-of-the-a
 rt\, I will provide perspectives as to how these approaches could be embed
 ded in larger systems.”
