PIMS - IAM Distinguished Colloquium: Elizabeth Crosson

Error correcting codes protect information by encoding it into a larger system with some redundancy, allowing the original logical information to be recovered even if part of the encoded system becomes lost or corrupted. In this talk I will introduce the theory of quantum error correcting codes (QECC), which depart from the classical case in surprising and beautiful ways in order to surmount some uniquely quantum hurdles: quantum information cannot be copied, and general measurements will disturb quantum states.
