Entanglement Distance of Two- and Multi-Qubit Variational States and Its Quantification with Quantum Computing

Kh. P. Gnatenko, R. O. Hredil, V. Y. Pinchuk +2

We study the entanglement distance of variational quantum states for two-qubit and multi-qubit systems. These states are constructed using variational quantum circuits with $R_Y$ r…
