Fault-Tolerant Resource Comparison of Qudit and Qubit Encodings for Diagonal Quadratic Operators
Samuel Godwood, DoÄa Murat KürkçüoÄlu, Gabriel N. Perdue +2
Finite local Hilbert-space truncations arise naturally in quantum simulations of lattice field theories and motivate qudit encodings, but their fault-tolerant advantage over qubit…

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…
