SUMMARY:Introduction to Quantum Error Correction: Schrödinger meets M
 axwell’s Demon\, Physics Department Colloquium\, Steven Girvin\, Yal
 e
DESCRIPTION:A ‘second quantum revolution’ is underway based on our
  new understanding of how information can be stored and manipulated us
 ing quantum hardware. Even more remarkable than the concept of quantum
  computation is the concept of quantum error correction. We know that 
 measurement ‘back action’ disturbs a quantum state when we observe
  it. Nevertheless\, it is possible to store an unknown quantum state a
 nd\, if it develops errors due to imperfect hardware\, we can measure 
 and correct such errors to recover the original unknown state. Crucial
 ly\, we must be able to do this without ever learning anything about t
 hat unknown state. This talk will present an elementary introduction t
 o the basic theoretical concepts underlying quantum error correction f
 or discrete systems (qubits) as well as for continuous-variable system
 s (harmonic oscillators).
