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…
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…
Enhancing Weak magnetic field sensing of cavity-magnon system with dual frequency modulation
Zheng Liu, Yu-qiang Liu, Zi-yi Mai +3
The crucial limitation of improving the sensitivity of the detection of weak magnetic fields is the unavoidable measurement noise. In this paper, we propose a scheme to achieve pre…
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…
Tight and attainable quantum speed limit for open systems
Zi-yi Mai, Chang-shui Yu
We develop an intuitive geometric picture of quantum states, define a particular state distance, and derive a quantum speed limit (QSL) for open systems. Our QSL is attainable beca…
