Quantum coherence-assisted secure communication of internet of things information via Landau-quantized graphene

Graphene-based nanotechnology in the Internet of Things: a mini review

“…Dihydrolevoglucosenone (Cyrene), a non-toxic solvent, was employed by Kewen Pan et al [ 58 ] to greatly accelerate and lower the cost of graphite's liquid phase exfoliation. The adjustable optical response of a recently suggested four-level ladder-type LQG subjected to two strong control fields and a weak probe field was reported by Azmat Iqbal Bashir [ 59 ]. For the safe exchange of quantum data through the Internet of Things quantum networking, they put out a quantum networking paradigm.…”

Bell-State-Exchange-Parity-Based Protocol for Efficient Autocompensation of Quantum Key Distribution Encoded in Polarization or Spatial Modes

“…Consequently, ω and ϕ are fully random in the wrapped range [0, 2π) for typical propagation distances in QKD. Since this effect is dominant, we even could neglect the dispersion of θ in Equation (8), which reduces to (9) with a completely random phase; consequently, Equation (10) predicts that X-base measurements provide no information at all: p X err = 1/2. The original BBM92 protocol does not work in this passive encoding due to the phase noise introduced by the fiber.…”

“…In particular, quantum key distribution (QKD) is indeed believed to be the ultimate solution to this problem, provided the laws of quantum mechanics are not disputed [5,6]. QKD is one of the most mature fields within the general context of quantum communications, i.e., communications that make use of quantum resources like coherence and entanglement [7] and profit from novel quantum material platforms [8]. However, QKD puts constraints on data bandwidths and achievable distances.…”
