Non-linear equation of motion for Page-Wootters mechanism with interaction and quasi-ideal clocks
Leandro R. S. Mendes, Frederico Brito, Diogo O. Soares-Pinto
Among the many proposals to approach the concept of time in quantum theory, the Page-Wootters mechanism has attracted much attention in the last few years. Originally, such a mecha…

Time as a Consequence of Internal Coherence
Leandro R. S. Mendes, Diogo O. Soares-Pinto
Time has been an elusive concept to grasp. Although we do not yet understand it properly, there has been advances made in regards to how we can explain it. One such advance is the…

Strong Subadditivity Lower Bound and Quantum Channels
L. R. S. Mendes, M. C. de Oliveira
We derive the strong subadditivity of the von Neumann entropy with a strict lower bound dependent on the distribution of quantum correlation in the system. We investigate the struc…
