Abstract

Optical computing accelerators, with high parallelism, large bandwidth, and low transmission loss, have the potential to enhance electronic computing in both computational power and energy efficiency. Photonic acceleration plays a crucial role in supporting computationally intensive operations, such as dynamic-static matrix multiplication, significantly improving overall efficiency. Existing photonic architectures for dynamic-static matrix multiplication depend on complex coherent optical systems or costly nano-optics fabrication, limiting scalability. This study introduces a novel quantum dot fluorescence-based dynamic-static matrix multiplication photonic acceleration architecture that eliminates the need for coherent light sources or intricate fabrication. By leveraging simple, cost-effective quantum dot preparation and printing techniques, this architecture has significant potential for large-scale, high-performance, low-cost photonic accelerators. We detail the mathematical and physical mechanisms of the proposed architecture, experimentally validate the key physical processes, and demonstrate its application in template matching for image recognition, achieving 95% accuracy.

Photonic-Implemented Efficient Deep Quantum Neural Network via Virtual-Driven Hilbert Space Expansion

Haoran Ma, Huihui Zhu, Zichao Zhao +10 more

The growing computational demands of classical neural networks have intensified the search for energy-efficient and powerful computational alternatives. Quantum neural networks (QNNs) implemented on integrated photonic platforms offer a compelling avenue, offering exceptional computational power enhancements, with inherent programmability and scalability of integrated architectures. A critical challenge, however, is implementing the fundamental non-unitary and nonlinear activation function of QNNs within a linear quantum photonic system. Existing strategies, such as the adding ancillary qubits and measurement-based feedback or forward are constrained by high qubit resource costs, overhead devices, and poor cascadability. Here, we propose a novel deep photonic QNN with an expanded computational Hilbert space via input replication and mode expansion, which enables the realization of effective non-unitary and nonlinear activation on a linear programmable quantum photonic chip. This approach eliminates the need for physical ancillary qubits, measurement-induced qubit consumption and the measurement device burden, thereby significantly reduce resource costs. The fabricated chip integrates four high-quality entanglement sources and a programmable high-dimensional interferometric network, enabling a two-hidden-layer QNN that exhibits dimension-enhanced expressivity over the existing QNN architectures. We demonstrate its capabilities across diverse tasks, including nonlinear classification, image generation, and quantum Gibbs state preparation. This work establishes a scalable and efficient architecture toward practical quantum deep learning systems capable of tackling problems beyond the reach of classical computation.
