Abstract
AbstractSimulation of materials by using quantum processors is envisioned to be a major direction of development in quantum information science. Here, the mathematical analogies between a triangular spin lattice with Dzyaloshinskii–Moriya coupling on one edge and a three‐level system driven by three fields in a loop configuration are exploited to emulate spin‐transport effects. It is shown that the spin transport efficiency, seen in the three‐level system as population transfer, is enhanced when the conditions for superadiabaticity are satisfied. It is demonstrated experimentally that phenomena characteristic to spin lattices due to gauge invariance, non‐reciprocity, and broken time‐reversal symmetry can be reproduced in the three‐level system.
Highlights
While large-scale quantum computers based on the trix elements; a multilevel system can be seen as a universal discrete gate model are still decades away, analog simulations simulator of spin chains with any type of interaction
We introduce the area of the counterdiabatic pulse 02 = √∫−∞∞ dt Ω02(t) and we define the stimulated Raman adiabatic passage (STIRAP) pulse area as = ∫−∞∞ dt Ω201(t) + Ω212(t) which is a measure of adiabaticity of the STIRAP process
We demonstrate that transport can be realized efficiently under the condition of superadiabaticity
Summary
Later in 1999 Seth Lloyd showed[2] that a universal quantum computer based on the gate model[3] can be used to solve the Schrödinger equation by the trotterization of its unitary evoreciprocality and broken time-reversal symmetry have been realized in nanomechanics[20,21,22,23] and in degenerate ultracold gases.[24]. In general, the spin Hamiltonian maps onto that of such digital simulations of spin systems have been recently of a multilevel system with driven transitions with complex marealized.[4,5] While large-scale quantum computers based on the trix elements; a multilevel system can be seen as a universal discrete gate model are still decades away, analog simulations simulator of spin chains with any type of interaction. We put in on small-scale quantum “emulators” are presently feasible.[6] evidence effects such as gauge invariance, chirality, broken-time
