Entanglement entropy of two disjoint intervals separated by one spin in a chain of free fermion
L. Brightmore, G. P. Geher, A. R. Its +4
We calculate the entanglement entropy of a non-contiguous subsystem of a chain of free fermions. The starting point is a formula suggested by Jin and Korepin, \texttt{arXiv:1104.10…
Bethe Ansatz for XXX chain with negative spin
Kun Hao, Dmitri Kharzeev, Vladimir Korepin
XXX spin chain with spin appears as an effective theory of Quantum Chromodynamics. It is equivalent to lattice nonlinear Schroediger's equation: interacting chain of harmoni…
Depth optimization of quantum search algorithms beyond Grover's algorithm
Kun Zhang, Vladimir E. Korepin
Grover's quantum search algorithm provides a quadratic speedup over the classical one. The computational complexity is based on the number of queries to the oracle. However, depth…
Quantum search on Hanoi network
Pulak Ranjan Giri, Vladimir Korepin
Hanoi network has a one-dimensional periodic lattice as its main structure with additional long-range edges, which allow having efficient quantum walk algorithm that can find a tar…
