To address the challenge of disparate benchmarking metrics across quantum computing architectures, a novel protocol-based strategy has been developed for comparing superconducting and ion-trap quantum technologies. This method employs rigorous binary fidelity thresholds, derived from classical state transfer limits, to directly quantify "quantumness" on optimal sub-chips. The approach provides a standardized framework for evaluating quantum advantage, thereby enabling direct performance comparisons between different quantum circuit technologies and establishing a critical foundation for future claims of quantum advantage.
This paper investigates the induction of pseudo-magnetic fields in strained honeycomb lattices, starting from a discrete tight-binding model. The authors derive a continuum effective magnetic Dirac Hamiltonian that governs wave packet dynamics near Dirac points. They demonstrate the existence of exponentially localized states with flat band spectra under specific unidirectional deformations, leading to high densities of states, and validate these findings with numerical simulations.
