Optimal convex approximation of quantum channels based on -affinity
Liqiang Zhang, Chengling Fu, Liuyong Cheng +2
Determining the minimal distance between a target channel and a convex hull of predefined set of implementable channels is a fundamental problem in quantum resource theory, and pro…
Dissipative Quantum Battery in the Ultrastrong Coupling Regime Between Two Oscillators
Yu-qiang Liu, Yi-jia Yang, Zheng Liu +6
In this work, we propose an open quantum battery that stores and releases energy by employing a two-mode ultrastrongly coupled bosonic system, with one mode (the charger) coupled t…
Dual effects of Lamb Shift in Quantum Thermodynamical Systems
Zi-chen Zhang, Chang-shui Yu
The Lamb shift as an additional energy correction induced by environments usually has a marginal contribution and hence is neglected. We demonstrate that the Lamb shift, which modi…
Attainable quantum speed limit for N-dimensional quantum systems
Zi-yi Mai, Chang-shui Yu
Quantum speed limit (QSL) is a fundamental concept in quantum mechanics and provides a lower bound on the evolution time. The attainability of QSL, greatly depending on the underst…
Family of attainable geometric quantum speed limits
Zi-yi Mai, Zheng Liu, Chang-shui Yu
We propose a quantum state distance and develop a family of geometrical quantum speed limits (QSLs) for open and closed systems. The QSL time includes an alternative function by wh…
Quantum Speed Limit in Terms of Coherence Variations
Zi-yi Mai, CHang-shui Yu
Coherence is the most fundamental quantum resource in quantum information processing. How fast a physical system gets coherence or decoherence is a critical ingredient. We present…
