Quantum computational advantage implies contextuality
Farid Shahandeh
We show that a separation between the class of all problems that can efficiently be solved on a quantum computer and those solvable using probabilistic classical algorithms in poly…
Ultrafine Entanglement Witnessing
Farid Shahandeh, Martin Ringbauer, Juan C. Loredo +1
Entanglement witnesses are invaluable for efficient quantum entanglement certification without the need for expensive quantum state tomography. Yet, standard entanglement witnessin…
Structural Quantification of Entanglement
F. Shahandeh, J. Sperling, W. Vogel
We introduce an approach which allows a detailed structural and quantitative analysis of multipartite entanglement. The sets of states with different structures are convex and nest…
A New Theorem on the Nonclassicality of States
F. Shähandeh, M. R. Bazrafkan
A new theorem on the non-classicality depth of states has been proved. We show that if exist for some value of the ordering parameter at some phase-spa…
