Entanglement Entropy with Lifshitz Fermions
Dion Hartmann, Kevin Kavanagh, Stefan Vandoren
We investigate fermions with Lifshitz scaling symmetry and study their entanglement entropy in 1+1 dimensions as a function of the scaling exponent . Remarkably, in the ground s…

Dynamical Phase Error in Interacting Topological Quantum Memories
Luuk Coopmans, Shane Dooley, Ian Jubb +2
A local Hamiltonian with Topological Quantum Order (TQO) has a robust ground state degeneracy that makes it an excellent quantum memory candidate. This memory can be corrupted howe…
