Artificial intelligence for representing and characterizing quantum systems
Yuxuan Du, Yan Zhu, Yuan-Hang Zhang +8
Efficient characterization of large-scale quantum systems, especially those produced by quantum analog simulators and megaquop quantum computers, poses a central challenge in quant…
TensorHyper-VQC: A Tensor-Train-Guided Hypernetwork for Robust and Scalable Variational Quantum Computing
Jun Qi, Chao-Han Huck Yang, Pin-Yu Chen +1
Variational Quantum Computing (VQC) faces fundamental scalability barriers, primarily due to barren plateaus and sensitivity to quantum noise. To address these challenges, we intro…
Large Parts are Generically Entangled Across All Cuts
Mu-En Liu, Kai-Siang Chen, Chung-Yun Hsieh +2
Generic high-dimensional bipartite pure states are overwhelmingly likely to be highly entangled. Remarkably, this ubiquitous phenomenon can already arise in finite-dimensional syst…
Almost device-independent calibration beyond Born's rule: Bell tests for cross-talk detection
Gelo Noel M. Tabia, Alex Yueh-Ting Shih, Jin-Yuan Zheng +1
In quantum information, device-independent protocols offer a new approach to information processing tasks, making minimal assumptions about the devices used. Typically, since these…
Nonlocality of Quantum States can be Transitive
Kai-Siang Chen, Gelo Noel M. Tabia, Chung-Yun Hsieh +2
