Spatial Incompatibility Witnesses for Quantum Temporal Correlations
Xiangjing Liu, Harshit Verma, Yunlong Xiao +2
We introduce a witness-based framework for certifying quantum temporal correlations via the pseudo-density matrix (PDM) formalism, which is a spatiotemporal generalization of the d…
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…
