Critical Schrödinger Cat Qubit
Luca Gravina, Fabrizio Minganti, Vincenzo Savona
Abstract
A bosonic code is proposed that makes use of both two-photon loss and Kerr nonlinearity, offering an enhanced performance over a broad range of detuning values and resistance to the random frequency shifts arising in multiple-qubit operations.
