Quantum causal inference via scattering circuits in NMR
Hongfeng Liu, Xiangjing Liu, Qian Chen +5
We report NMR scattering circuit experiments that reveal causal structure. The scattering circuit involves interacting a probe qubit with the system of interest and finally measuri…
Experimental demonstration of quantum causal inference via noninvasive measurements
Hongfeng Liu, Xiangjing Liu, Qian Chen +5
We probe the foundations of causal structure inference experimentally. The causal structure concerns which events influence other events. We probe whether causal structure can be d…
Experimental Validation of Enhanced Information Capacity by Quantum Switch in Accordance with Thermodynamic Laws
Cheng Xi, Xiangjing Liu, Hongfeng Liu +6
We experimentally probe the interplay of the quantum switch with the laws of thermodynamics. The quantum switch places two channels in a superposition of orders and may be applied…
