Interplay between teleportation fidelity and basis-independent coherence in maximally sliced states under decoherence

Decoherence significantly impacts the fidelity of quantum teleportation, particularly when using the three-qubit Maximally Sliced state as a shared resource. Researchers have derived analytical expressions for teleportation fidelity under amplitude damping and phase damping channels using the Kraus operator formalism¹. This approach enables the quantification of basis-independent coherence, which is crucial for understanding the interplay between decoherence and teleportation fidelity. The study reveals that environmental decoherence can substantially degrade the quality of quantum teleportation, emphasizing the need for robust methods to mitigate its effects. The findings have significant implications for the development of reliable quantum communication protocols. So what matters to practitioners is that understanding the relationship between decoherence and teleportation fidelity is essential for designing and implementing secure quantum computing systems.
