摘要

Abstract

Quantum nanophotonics merges the precision of nanoscale light manipulation with the capabilities of quantum technologies

offering a pathway for enhanced light-matter interaction and compact realization of quantum devices. Here

we show how a recently-demonstrated nonlinear nanophotonic process can be employed to selectively create photonic high-dimensional quantum states (qudits). We utilize the nonlinearity on the surface of the nanophotonic device to dress

through the polarization of the pump field

the near-field modes carrying angular momentum and their superpositions. This idea is an important step towards experimental realizations of quantum state generation and manipulation through nonlinearity within nanophotonic platforms

and enables new capabilities for on-chip quantum devices.
