Experimental Demonstration of a Versatile and Scalable Scheme for Iterative Generation of Non-Gaussian States of Light

Year: 2024

Type: article

Abstract: Non-Gaussian states of light, such as Gottesman-Kitaev-Preskill states, are essential resources for optical continuous-variable quantum computing. The ability to efficiently produce these states would open up tremendous prospects for quantum technologies in general and fault-tolerant quantum computing in particular. This letter demonstrates a versatile method using a quantum-memory cavity to mitigate the consequences of the probabilistic nature of the breeding protocols and generate non-Gaussian states at high rates with scalability perspectives. The performances of our experimental setup are illustrated with the generation of squeezed cat states of amplitude α=1.63 with a fidelity of more than 60% at a generation rate in the kHz range, which is higher than the state of the art for such states.
