Hierarchy in temporal quantum correlations
Huan-Yu Ku, Shin-Liang Chen, Neill Lambert +2
Einstein-Podolsky-Rosen (EPR) steering is an intermediate quantum correlation that lies in between entanglement and Bell non-locality. Its temporal analogue, temporal steering, has…
Einstein-Podolsky-Rosen steering: Its geometric quantification and witness
Huan-Yu Ku, Shin-Liang Chen, Costantino Budroni +3
We propose a measure of quantum steerability, namely a convex steering monotone, based on the trace distance between a given assemblage and its corresponding closest assemblage adm…
Thermodynamic description of non-Markovian information flux of nonequilibrium open quantum systems
Hong-Bin Chen, Guang-Yin Chen, Yueh-Nan Chen
One of the fundamental issues in the field of open quantum systems is the classification and quantification of non-Markovianity. In the contest of quantity-based measures of non-Ma…
Work extraction and fully entangled fraction
Chung-Yun Hsieh, Ray-Kuang Lee
For a bipartite state with equal local dimension d, we prove that one can obtain work gain under Landauer's erasure process on one party in identically and independently distribute…
Universal measurement-based quantum computation in two-dimensional SPT phases
Tzu-Chieh Wei, Ching-Yu Huang
Recent progress in characterization for gapped quantum phases has also triggered the search of universal resource for quantum computation in symmetric gapped phases. Prior works in…
Optical Density-Enhanced Squeezed Light Generation without Optical Cavities
You-Lin Chuang, Ray-Kuang Lee, Ite A. Yu
To achieve high degree of quantum noise squeezing, an optical cavity is often employed to enhance the interaction time between light and matter. Here, we propose to utilize the eff…
