Non-Gaussian quantum states of a multimode light field

摘要: Advanced quantum technologies require scalable and controllable resources1,2. Gaussian states of multimode light, such as squeezed cluster states, are systems3–5, which can be generated on demand. However, non-Gaussian features indispensable in many protocols, especially to reach a computational advantage6. Embodying non-Gaussianity state remains challenge operations generally cannot maintain coherence among multiple modes. Here, we generate light field by removing single photon mode-selective manner from state7. To highlight the potential for continuous-variable technologies, first demonstrated capability negativity Wigner function controlled mode. Subsequently, explored interplay between entanglement verify theoretical prediction8 about propagation along nodes photon-subtracted states. Our results demonstrate large-scale with great flexibility an ensured compatibility information protocols. This range makes our approach ideal explore physics entanglement9,10 develop across computing11,12, distillation13 simulations14. Continuous-variables processing requires operations. The generation is now reported through photon-subtraction scheme
