SUMMARY:Adventures in Quantum Phase Space: Why Bosons are Better than Qubits for Quantum Error Correction
LOCATION:Zoom
DESCRIPTION:The fact that quantum error correction is possible in principle is, in many
  ways, far more amazing than the idea of quantum computation itself.  Quant
 um computers are analog devices and yet they evade the no-go theorem that p
 recludes error correction in classical analog computers.  The grand challen
 ge of the field is to realize quantum error correction in practice.  This t
 alk will review the basics of quantum error correcting codes for qubits and
  then demonstrate that there are enormous practical advantages in using cod
 es based on superpositions of small numbers of microwave photon states.  Ex
 perimental realizations of various newly developed ‘bosonic codes’ have suc
 cessfully approached and for the first time have even exceeded the threshol
 d where quantum error correction begins to extend the lifetime of quantum i
 nformation.\n \n
