Experimental realization of quantum Zeno dynamics for robust quantum metrology
Ran Liu, Xiaodong Yang, Xiang Lv +5
Quantum Zeno dynamics (QZD), which restricts the system's evolution to a protected subspace, provides a promising approach for protecting quantum information from noise. Here, we e…
Reversing Heat Flow by Coherence in a Multipartite Quantum System
Keyi Huang, Qi Zhang, Xiangjing Liu +12
The second law of thermodynamics dictates that heat flows spontaneously from a high-temperature entity to a lower-temperature one. Yet, recent advances have demonstrated that quant…
Recovering optimal precision in quantum sensing with time domain imperfections
Zi-Shen Li, Xinyue Long, Xiaodong Yang +2
Quantum control plays a crucial role in enhancing precision scaling for quantum sensing. However, most existing protocols require perfect control, even though real-world devices in…
Neural quantum embedding via deterministic quantum computation with one qubit
Hongfeng Liu, Tak Hur, Shitao Zhang +10
Quantum computing is expected to provide exponential speedup in machine learning. However, optimizing the data loading process, commonly referred to as quantum data embedding, to m…
