“…Such robustness on the multiple cases of mode mismatch is made possible because of the fully degenerate nature of the self-imaging OPO, which cannot be accomplished by using a confocal OPO 18 or two single-mode OPOs 16 . Our work of mitigating the mode mismatching loss will have broad applications to quantum technologies based on squeezed light, e.g., quantum-enhanced gravitational-wave detection 11 , 12 , deterministic quantum teleportation 7 , measurement-based quantum computing 1 4 , and Gaussian boson sampling 5 , 6 .…”

“…This problem corresponds to the renowned Gaussian Boson sampling (Hamilton et al 2017;Quesada et al 2018), which recently demonstrated the quantum advantage at an impressing scale (Zhong et al 2020), following earlier realizations (Tillmann et al 2012;Broome et al 2013;Spring et al 2013;Spagnolo et al 2014;Carolan et al 2014;Wang et al 2019) of the original proposal by Aharanson and Arkhipov (Aaronson and Arkhipov 2013). The theory of Gaussian Boson sampling (GBS) heavily relies on phase-space methods (Kruse et al 2019), making it an exciting NN test-bed supported by recently reported trainable hardware (Arrazola et al 2021;Hoch et al 2021;Zhong et al 2021).…”

“…In this paper, we present two photonic integrated reconfigurable linear processors based on 2 × 2 interferometric elements [5]. These devices are versatile, being exploited over the years for optical processing and filtering [6], programmable true-time optical delay lines [7], and quantum information processing [8,9]. They are also suited for realizing the linear operations (i.e., matrix-vector multiplications) required in each DNN layer.…”
