Multi-Qubit Entanglement Visualization

Abstract

The quantum computing, quantum cryptography and quantum communication protocols are pillars on the quantum
entanglement with GreenbergerHorneZeilinger (GHZ) states. The fact of multi-qubit entangled states is difficult to
intuitively interpret although it is important theoretically even in the noise and decoherence case. In this paper, it is
proposed to present the quantum simulator that aims to create and simulate and visualize various qubit GHZ states in
three popular quantum noise models including the depolarizing, amplitude and phase damping. The system is coded
in Flask and the Qiskit and Qiskit Aer on the circuit building and circulation and the Matplotlib on the heatmap of the
density matrices, bar plots in three dimensions, and the Bloch sphere. One of them is that it can be parameterized with
an amplitude coefficient 8 that can be used to research unequal entanglement amplitude parameter of interest in
quantum secret sharing applications. It is based on containers and can be obtained using Docker, as well as can be
viewed using any current browser and the localization of quantum frameworks is not necessary. The dynamics of the
simulation demonstrates that the system is a good model of the theoretical behavior of the noise: depolarizing noise
takes states to the maximum mixture, amplitude damping takes the populations to ground states and phase damping
selectively decays the coherences. It is applied by teachers and learners, and researchers who were interested in
obtaining an interactive and graphical interface that allows offering an interface between the abstract quantum
formalism and the real quantum dynamics of information.
