Article Title: Entropy, Fidelity, and Entanglement During Digitized Adiabatic Quantum Computing to Form a Greenberger–Horne–Zeilinger (GHZ) State
doi: 10.3390/e27090891
Figure Lengend Snippet: GHZ witness evaluated as a function of the discretized adiabatic quantum computing step for the Python calculations and the quantum simulators Fake Perth, Fake Aachen, Fake Brisbane, and Fake Sherbrooke. The density matrices from Python calculations and from the simulators clearly incorporate a GHZ component, except for Fake Perth.
Article Snippet: We denote the trace of the product of the GHZ witness operator with the density matrix as the “GHZ witness” (as distinct from the GHZ witness operator).
