Engineering the quantum states of light in a Kerr-nonlinear resonator by two-photon driving

Quantum Computing: An engineered quantum box for Schrodinger’s cat Efficient preparation of the so called photonic Schrodinger’s cat states, is possible by engineering the energy levels in a quantum box. We propose an approach for fast, high-fidelity preparation and manipulation of cat states in a n...
