Towards realization of universal quantum teleportation using weak measurements (2307.09231v4)

Published 18 Jul 2023 in quant-ph

Abstract: In this manuscript, we analyze universal quantum teleportation in the presence of memory or memory-less dynamics with applications of partial collapse measurement operators. Our results show that the combined effects of memory or non-Markovianity and weak measurements can lead to universal quantum teleportation (UQT). Our study involves noise models of physical importance having characteristic Markovian and non-Markovian regions allowing one to observe a transition in quantum properties as one switches from non-Markovian to Markovian dynamics. For this, we characterize the effects of different types of non-Markovianity for efficient UQT both due to retention of correlations for a longer duration and due to information backflow. We further analyze memory effects arising from a correlated channel with or without weak measurements. Interestingly, our analysis for a correlated amplitude damping channel shows that memory effects are of significant advantage to minimize the fidelity deviation. The presence of weak measurements further enhances the realization of UQT in the presence of memory. The ability of memory effects in achieving zero fidelity deviation at non-zero time is interesting and of experimental importance.
