In minisymposium: Linear Algebra and Quantum ComputationWed 12:00–12:30, Auditorium Jean Monnet
The idea of quantum error correction is to protect quantum information from errors due to decoherence and other quantum noise during the transmission of information in quantum channels. In this talk, we consider the situation when all physical qubits involved in coding suffer from the same error operators. A recursive error correcting scheme and its implementing encoding and decoding quantum circuits will be presented. The result will also be extended to the qudit case. This talk is based on joint works with Güngördü, Li, Nakahara, Poon, and Tomita.
