This article provides the unconditional security of a semi quantum key distribution (SQKD) protocol based on 3-dimensional states. By deriving lower bound for rate, in asymptotic scenario, as function channel’s noise, we find that this has improved secret rate with much more tolerance noise compared to previous 2-dimensional SQKD protocol. Our results highlight that, similar fully protocol, inc...

Precise measurements of parameters in the PMNS framework might lead to new physics beyond Standard Model. However, they are incredibly challenging determine neutrino oscillation experiments. Quantum simulations can be a powerful supplementary tool study these phenomenologies. In today's noisy quantum hardware, encoding neutrinos multi-qubit system requires redundant basis and tricky entangling ...

Abstract Quantum teleportation is the fundamental communication unit in quantum communication. Here, a three-level system selected for storing and transmitting information, due to its unique advantages, such as lower cost than higher-level higher capacity security two-level system. It known that key procedure perfect distribution of entanglement through channel. However, amounts noise existing ...

We obtain the exact analytical solution for continuously driven qutrit in V and $\Lambda$ configurations governed by Lindblad master equation. calculate linear susceptibility each system, determining regimes of transient gain without inversion, identify parameter values superluminal, vanishing, negative group velocity probe field.
