Intrinsic decoherence effects on correlated coherence and quantum discord in XXZ Heisenberg model
Zakaria Dahbi, Mansoura Oumennana, Mostafa Mansour
Spin qubits are at the heart of technological advances in quantum processors and offer an excellent framework for quantum information processing. This work characterizes the time e…
Effect of induced transition on the quantum entanglement and coherence in two-coupled double quantum dots system
Zakaria Dahbi, Maron F. Anka, Mostafa Mansour +2
Studying quantum properties in solid-state systems is a significant avenue for research. In this scenario, double quantum dots (DQDs) appear as a versatile platform for technologic…
Geometrical, topological and dynamical description of interacting spin- under long-range Ising model and their interplay with quantum entanglement
Brahim Amghar, Abdallah Slaoui, Jamal Elfakir +1
Comprehending the connections between the geometric, topological, and dynamical structures of integrable quantum systems with quantum phenomena exploitable in quantum information t…
A simple analytical expression of quantum Fisher and Skew information and their dynamics under decoherence channels
Nour-Eddine Abouelkhir, Hanane EL Hadfi, Abdallah Slaoui +1
In statistical estimation theory, it has been shown previously that the Wigner-Yanase skew information is bounded by the quantum Fisher information associated with the phase parame…
Controlled quantum teleportation between discrete and continuous physical systems
M. El Kirdi, A. Slaoui, N. Ikken +2
Quantum teleportation of an unknown state basing on the interaction between discrete-valued states (DV) and continuous-valued states (CV) presented a particular challenge in quantu…
Mutually Unbiased Bases In 3 and 4 Dimensions Semi-quantum Key Distribution Protocol
Hasnaa Hajji, Morad El Baz
Semi-quantum key distribution is traditionally based on two-level quantum systems. In this paper, an unconditional security of a semi quantum key distribution protocol based on hig…
