From coherence to mixedness: a driver of barren plateaus in variational quantum algorithms
Xiang Zhou
Variational quantum algorithms (VQAs) are a leading approach for near-term quantum advantage. However, their training is often hindered by barren plateaus (BPs). We present a frame…

Distribution of distance-based quantum resources outside a radiating Schwarzschild black hole
Samira Elghaayda, Xiang Zhou, Mostafa Mansour
We obtain analytical expressions for distance-based quantum resources and examine their distribution in the proximity of a Schwarzschild black hole (SBH) within a curved background…
