Entropy, 2023•mdpi.comIn this paper, we derive a quantum speed limit for unitary evolution for the case of mixed
quantum states using the stronger uncertainty relation for mixed quantum states. This bound
can be optimized over different choices of Hermitian operators for a better bound. We
illustrate this with some examples and show its better performance with respect to three
existing bounds for mixed quantum states.
