Harnessing strong symmetry breaking finite-component system phase transition for quantum error correction
Yanzhang Zhu, Myung-Joong Hwang · Quantum 2.0 Conference and Exhibition · 2024
We investigate a dissipative finite-component system phase transition induced by two photon loss mechanism, which features a strong symmetry breaking of the Liouvillian. We characterize the mean-field phase diagram and demonstrate that the system could be harnessed to implement passive error correction for a hybrid qubit-oscillator qubit.
