Efficient learning of bosonic unitaries beyond the Gaussian class
Xiaobin Zhao, Quntao Zhuang
The paper studies how to efficiently learn multimode bosonic unitary processes that go beyond Gaussian operations, showing that while general unitaries require exponential resource…
Theory Framework of Multiplexed Photon-Number-Resolving Detectors
Xiaobin Zhao, Hezheng Qin, Hong X. Tang +2
Photon counting is a fundamental component in quantum optics and quantum information. However, implementing ideal photon-number-resolving (PNR) detectors remains experimentally cha…
Complexity of quantum tomography from genuine non-Gaussian entanglement
Xiaobin Zhao, Pengcheng Liao, Francesco Anna Mele +2
Quantum state tomography, a fundamental tool for quantum physics, usually requires a number of state copies that scale exponentially with the system size, owing to the intricate qu…
Quantum illumination networks
Xiaobin Zhao, Zheshen Zhang, Quntao Zhuang
Quantum illumination is an entanglement-based target detection protocol that provides quantum advantages despite the presence of entanglement-breaking noise. However, the advantage…
