No Practical Quantum Broadcasting: Even Virtually
Yunlong Xiao, Xiangjing Liu, Zhenhuan Liu
Quantum information cannot be broadcast -- an intrinsic limitation imposed by quantum mechanics. However, recent advances in virtual operations offer new insights into the no-broad…
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…
Certifying Quantum Temporal Correlation via Randomized Measurements: Theory and Experiment
Hongfeng Liu, Zhenhuan Liu, Shu Chen +3
We consider the certification of temporal quantum correlations using the pseudo-density matrix (PDM), an extension of the density matrix to the time domain, where negative eigenval…
Quantum harvester enables energy transfer without randomness transfer or dissipation
Fei Meng, Junhao Xu, Xiangjing Liu +1
We consider a foundational question in energy harvesting: given a partly random energy source, is it possible to extract the energy without also transferring randomness or acceptin…
Quantum Causal Inference with Extremely Light Touch
Xiangjing Liu, Yixian Qiu, Oscar Dahlsten +1
We give a causal inference scheme using quantum observations alone for a case with both temporal and spatial correlations: a bipartite quantum system with measurements at two times…
