SWAP and Transpose by displacements, Stabilizer Renyi entropies for continuous variables and qudits and other applications
Israel Klich
In this note, I highlight a useful formula for the SWAP operator as an average of anti-correlated Heisenberg-Weyl displacements, valid for arbitrary-dimensional quantum systems. As…

Confinement and Kink Entanglement Asymmetry on a Quantum Ising Chain
Brian J. J. Khor, D. M. Kürkçüoglu, T. J. Hobbs +2
In this work, we explore the interplay of confinement, string breaking and entanglement asymmetry on a 1D quantum Ising chain. We consider the evolution of an initial domain wall a…
