Finite stellar rank creates a trade-off between state-preparation cost and QEC performance for bosonic codes, with rank k=2 optimized encodings surpassing break-even under dephasing.
A driven-dissipative model of a two-mode superconducting circuit with self- and cross-Kerr nonlinearities demonstrates enhanced TRSB detection via symmetric photon configurations broken by weak symmetry breaking.
