Spectral geometric mean and trace characterizations
Airat Bikchentaev, Trung Hoa Dinh, Anh Vu Le +1
We use nearly parallel pure states to characterize positive linear functionals on as positive multiples of the trace if and only if $Ï(A \natural B) \leq \sqrt…

A new estimation of the quantum Chernoff bound
Mohsen Kian, Trung Hoa Dinh, Mohammad Sal Moslehian +1
Relating to finding possible upper bounds for the probability of error for discriminating between two quantum states, it is well-known that \begin{align*} \mathrm{tr}(A+B) - \mathr…
