Coherence monotones of quantum channels based on two generalized quantum relative entropies
By using the Choi-Jamiołkowski isomorphism, we propose two classes of coherence monotones of quantum channels based on the unified $(r,s)$-relative entropy and the sandwiched Rényi relative entropy. Elegant properties of the coherence monotones for quantum channels are explored. Moreover, we present the upper bounds of the coherence monotones and derive the explicit formulas of the coherence monotones for qubit unitary channels.

The dollar sank to its lowest level in more than three years on Thursday
and the FTSE 100 closed at a record high as Donald Trump’s latest trade threats and the weakening economy appeared to bring forward interest rate cuts by the Federal Reserve.
Foreign exchange traders sold the dollar in favour of the yen and the euro,
which both climbed by about 1% against the US currency to leave it almost 10% down on its value against a basket of currencies since the beginning of the …

The built in calculator app on the iPhone can do all sorts of conversions.
Long-press the icon at bottom left and you get a pop-up menu. Slide the toggle on and the default $ to € currency converter appears. There’s a bazillion other currencies available too. But you can also choose among 15 other unit conversions, like weights, energy, force, pressure.

Quantifying coherence of quantum channels based on the generalized $α$-$z$-relative Rényi entropy
By using the Choi-Jamiołkowski isomorphism, we propose a well-defined coherence measure of quantum channels based on the generalized $α$-$z$-relative Rényi entropy. In addition, we present an alternative coherence measure of quantum channels by quantifying the commutativity between the channels and the completely dephasing channels with the generalized $α$-$z$-relative Rényi entropy. Some elegant properties of the measures are illustrated in detail. Explicit formulas of these coherence mea…

Uncertainty relations for unified ($\alpha$,$\beta$)-relative entropy of coherence under mutually unbiased equiangular tight frames

Uncertainty relations for unified ($α$,$β$)-relative entropy of coherence under mutually unbiased equiangular tight frames
Uncertainty relations based on quantum coherence is an important problem in quantum information science. We discuss uncertainty relations for averaged unified ($α$,$β$)-relative entropy of coherence under mutually unbiased equiangular tight frames, and derive an interesting result for different parameters. As consequences, we obtain corresponding results under mutually unbiased bases, equiangular tight frames or based on Tsallis $α$- relative entropies and Rényi-$α$ relative entropies. We …
