Warsaw Quantum Computing Group – Episode XXXVII, Aleksandra Lipińska, “Surface Code Design for Asymmetric Error Channels”

Abstract:
Surface codes are quantum error-correcting codes normally defined on 2D arrays of qubits. During the lecture, a new surface code design will be introduced, based on the fact that the severity of bit-flip and phase flip errors in the physical quantum systems is asymmetric. For the proposed surface code design for asymmetric error channels, results of several experiments will be presented, utilizing the presence of various degrees of asymmetry of Pauli X, Y , and Z errors in a depolarisation channel.
