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…
Realizing Universal Non-Markovian Noise Suppression
Hongfeng Liu, Zizhao Han, Xinfang Nie +2
Non-Markovian noise, arising from environmental memory effects, is the most general and challenging form of noise in quantum computing, and is typically difficult to characterize a…
Noise-Resilient Quantum Metrology with Quantum Computing
Xiangyu Wang, Chenrong Liu, Xue Lin +8
Quantum computing has made remarkable strides in recent years, as demonstrated by quantum supremacy experiments and the realization of high-fidelity, fault-tolerant gates. However,…
Experimental Virtual Quantum Broadcasting
Yuxuan Zheng, Xinfang Nie, Hongfeng Liu +3
The quantum no-broadcasting theorem states that it is fundamentally impossible to perfectly replicate an arbitrary quantum state, even if correlations between the copies are allowe…
Strain Enhanced Spin Readout Contrast in Silicon Carbide Membranes
Haibo Hu, Guodong Bian, Ailun Yi +12
Quantum defects in solids have emerged as a transformative platform for advancing quantum technologies. A key requirement for these applications is achieving high-fidelity single-s…
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…
