Quantum computers are on the brink of surpassing the capabilities of even the most powerful classical computers, which naturally raises the question of how one can trust the results of a quantum computer when they cannot be compared to classical simu

Graphene-metal heterostructures can confine the optical field down to the atomic level. We report record enhancement of high-harmonic generation and demonstrate, for the first time, that plasmons can indeed affect the graphene nonlinear optical respo

A Near Deterministic Plasmonic Quantum Zeno Gate using Graphene Nanoribbons

Autor: Lee A. Rozema, Joel D. Cox, Philip Walther, I. Alonso Calafell, J. Garcia de Abajo, Milan Radonjić

Publikováno v: Conference on Lasers and Electro-Optics.

The scalability of photonic quantum-computation is limited by the low success probability of two-qubit logic gates. We propose a root-SWAP gate based on graphene nanoribbons, where the strong two-plasmon absorption boosts its success above 90%.
