Periodic conditional measurements on a photonic chip
Xuan Chen, Ruo-Yu Yin, Xiao-Wen Shang +10
Quantum measurements not only extract information but also reshape quantum evolution through measurement backaction. Here, we investigate periodic conditional measurements, in whic…
QuLoC: Photonic Quantum-Assisted Low-Rank LLM Compression
Xiao-Hui Ni, Yu-Han Yao, Yu-Ze Zhu +4
As LLMs grow in size, compression becomes increasingly important for efficient deployment. SVD-based low-rank compression reduces parameter counts but can degrade downstream perfor…
A Chip-scale Space-time Multiplexed Gaussian Boson Sampling Processor Beyond 10,000 Photons
Yu-Xuan Fu, He-Yu Shen, Ke-Ming Hu +33
Gaussian boson sampling (GBS) has emerged as a leading photonic paradigmfor demonstrating quantum computational advantage. Nevertheless, state-ofthe-art GBS setups face practical b…
Spatiotemporally Interleaved Homodyne Photonic Tensor Core
Yun-Long Nie, Hang Song, De-Hui Huang +6
Photonic computing provides ultrahigh bandwidth, low latency and intrinsic parallelism, making it a promising route beyond the scaling limits of electronic computing. However, exis…
Instantaneous velocity during quantum tunnelling
Xiao-Wen Shang, Jian-Peng Dou, Feng Lu +3
Quantum tunnelling, a hallmark phenomenon of quantum mechanics, allows particles to pass through the classically forbidden region. It underpins fundamental processes ranging from n…
DeepQuantum: A PyTorch-based Software Platform for Quantum Machine Learning and Photonic Quantum Computing

Quantum interference and entanglement are in the core of quantum computations. The fast spread of information in the quantum circuit helps to mitigate the circuit depth. Although t…
Codesigned counterdiabatic quantum optimization on a photonic quantum processor
Xiao-Wen Shang, Xuan Chen, Narendra N. Hegade +6
Codesign, an integral part of computer architecture referring to the information interaction in hardware-software stack, is able to boost the algorithm mapping and execution in the…
A Test of Empty Wave via Quantum Memory in a Weak Measurement Scheme
Jian-Peng Dou, Feng Lu, Hao Tang +2
In quantum mechanics, a long-standing question remains: How does a single photon traverse double slits? One intuitive picture suggests that the photon passes through only one slit,…
Regeneration of Spin Wave in Atomic Vapor
Jian-Peng Dou, Feng Lu, Xiao-Wen Shang +2
Conventionally, atomic vapor is perceived as a non-living system governed by the principles of thermodynamics and statistical physics. However, the demarcation line between life an…
