Bimodal behavior of measurement-dependent one-way quantum deficit for two-qubit X states

2017 · arXiv (Cornell University)

It is shown that in some regions of X-state space the measurement-dependent one-way quantum deficit \Delta as a function of measurement angle \theta\in[0,\pi/2] exhibits a bimodal behavior inside the open interval (0,\pi/2), i.e., it has …

A comparative study of LQU and LQFI in general qubit-qutrit axially symmetric states

2024 · arXiv (Cornell University)

We derive the compact closed forms of local quantum uncertainty (LQU) and local quantum Fisher information (LQFI) for hybrid qubit-qutrit axially symmetric (AS) states. This allows us to study the quantum correlations in detail and …
