英文摘要Large optical nonlinearities can create fancy physics, such as the big Schrodinger-cat state and quadrature squeezing. We present the possibility to practically generate macroscopic Schrodinger-cat states, based on a giant Kerr nonlinearity, in a diamond nitrogen-vacancy ensemble interacting with two coupled flux-qubits. The nonlinearity comes from a four-level N-type configuration formed by two coupled flux-qubits under the appropriately driving fields. We discuss the experimental feasibility in the presence of system dissipations using current laboratory technology and our scheme can be easily extended to other ensemble systems.
