Estimation on Geometric Measure of Quantum Coherence

We study the geometric measure of quantum coherence recently proposed in (Phys. Rev. Lett. 115(2015)020403)Both lower and upper bounds of this measure are provided. These bounds are shown to be tight for a class of important coherent states—maximally coherent mixed states. The trade-off relation bet...

Summary:We study the geometric measure of quantum coherence recently proposed in (Phys. Rev. Lett. 115(2015)020403)Both lower and upper bounds of this measure are provided. These bounds are shown to be tight for a class of important coherent states—maximally coherent mixed states. The trade-off relation between quantum coherence and mixedness for this measure is also discussed.
