Photonic implementation of quantum hidden subgroup database compression
Qianyi Wang, Feiyang Liu, Teng Hu +6
We experimentally demonstrate quantum data compression exploiting hidden subgroup symmetries using a photonic quantum processor. Classical databases containing generalized periodic…
Page Curve of average subsystem entropy
Oscar C. O. Dahlsten
The Page curve is a curve of average subsystem entropy as a function of subsystem size. The curve starts from 0, rises, peaks near the maximal possible entropy when the subsystem m…
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…
Inferring the arrow of time in quantum spatiotemporal correlations
Xiangjing Liu, Qian Chen, Oscar Dahlsten
We consider how to tell the time-ordering associated with measurement data from quantum experiments at two times and any number of qubits. We define an arrow of time inference prob…
