Benchmarking Quantum State Transfer on Quantum Devices using Spatio-Temporal Steering
Yi-Te Huang, Jhen-Dong Lin, Huan-Yu Ku +1
Quantum state transfer (QST) provides a method to send arbitrary quantum states from one system to another. Such a concept is crucial for transmitting quantum information into the…
Experimental test of non-macrorealistic cat-states in the cloud
Huan-Yu Ku, Neill Lambert, Fong-Ruei Jhan +3
The Leggett-Garg inequality attempts to classify experimental outcomes as arising from one of two possible classes of physical theories: those described by macrorealism (which obey…
Experimental demonstration of measurement-device-independent measure of quantum steering
Yuan-Yuan Zhao, Huan-Yu Ku, Shin-Liang Chen +6
Within the framework of quantum refereed steering games, quantum steerability can be certified without any assumption on the underlying state nor the measurements involved. Such a…
Measurement-device-independent measure of steerability and witnesses for all steerable resources
Huan-Yu Ku, Shin-Liang Chen, Hong-Bin Chen +2
The fact that nonlocality implies steering enables one to certify steerability by using a Bell inequality violation. Such a certification is device-independent (DI), i.e., one make…
Probing higher-order transitions through scattering of microwave photons in the ultrastrong-coupling regime of circuit QED
Guan-Ting Chen, Po-Chen Kuo, Huan-Yu Ku +2
Higher-order transitions can occur in the ultrastrong-coupling regime of circuit QED through virtual processes governed by the counter-rotating interactions. We propose a feasible…
