| الوصف: | Photonics is a promising platform for demonstrating a quantum computational advantage QCA by outperforming the most powerful classical supercomputers on a well defined computational task. Despite this promise, existing proposals and demonstrations face challenges. Experimentally, current implementations of Gaussian boson sampling GBS lack programmability or have prohibitive loss rates. Theoretically, there is a comparative lack of rigorous evidence for the classical hardness of GBS. In this work, we make progress in improving both the theoretical evidence and experimental prospects. We provide evidence for the hardness of GBS, comparable to the strongest theoretical proposals for QCA. We also propose a QCA architecture we call high dimensional GBS, which is programmable and can be implemented with low loss using few optical components. We show that particular algorithms for simulating GBS are outperformed by high dimensional GBS experiments at modest system sizes. This work thus opens the path to demonstrating QCA with programmable photonic processors |
